astrokit's Issues

As a user, I want to add or remove AnalysisResult objects while viewing a Lightcurve plot

On the lightcurve creation page, users should be able to add or remove AnalysisResult objects (each of these AnalysisResults adds one point to the light curve)

As a user, I want to trigger a reduction run by pressing a button

Reductions are dependent on user-tuned parameters, so we should be able to run and re-run reductions whenever the user wants.

As a user, I want to choose target in the first step

It's too annoying to go 3 pages deep just to choose the target

As a user, I want reductions to be performed for all point sources, including unknowns

Right now they are performed only for the knowns. ra, dec needs to be computed for unknown point sources.

As a reduction user, I also want to correct for light time and phase angle

See chapter 13 of Brian Warner's book

As a newbie user, I want to be told when second-order extinction is needed.

it defaults to 0 and is only needed for certain filters. Add some text to make this clear.

As a user, I want to have control over the images in my light curve

I want to select images and

• omit them from the curve**
• include them in the curve**
• delete them
• move them to other light curves

As a site visitor, I want to learn about AstroKit

Fill Astrokit homepage with content.

As a user, I want to add a new image to a LightCurve

After performing initial upload, allow user to add more images

As a user, I want to name my AnalysisResult

Each image produces an AnalysisResult, so a user may have a lot of AnalysisResults. Rather than referring to them by ID#, it would be easier if the user could label them arbitrarily. This should be done on the first edit page for AnalysisResults.

The name of the AnalysisResult should display in the list of a user's images (and in other UIs that include lists of AnalysisResults, such as when selecting an AR to add to a Lightcurve)

As a user, I want to set global defaults on the Lightcurve page for image inputs

Rather than making the same inputs for every image, I want to set some defaults at the top of the light curve page.

As a user, I want to view magnitudes overlaid on an image.

The output of the reduction step should include an image overlay with point sources highlighted. On mouseover, reveal the magnitudes (similar to the comparison star viewer)

As a developer, I want to see documentation online

As an asteroid astronomer, I want to see the temperature of catalog stars

Asteroid users will want to filter the set of potential comparison stars to those that have color similar to the sun.

As a user, I want to set default values for astrometry and reduction across all images in a lightcurve

At the top of the light curve page, have a form that contains all user inputs. These inputs will be the default values in the AnalysisResult astrometry->photometry->reduction flow.

As a prospective user, I want to view a test dataset before I upload my own data

Find a good test dataset that we can showcase end-to-end so that new and prospective users know what they can get. This also doubles as a good test for our own scientific calculations.

As a user, I want to select potential comparison stars for inclusion in my calculations.

Currently all comparison stars are used in reductions. But astronomers won't always want this. We should present the information and let the astronomer choose.

As a reduction user, I want to compute standard mag of target star

As a user, I want load Terminology, FAQs, Contact Us page

Create placeholders for these pages using the template

As a user, I want to see corrected magnitudes for all point sources in the image

In the reduction step, we should compute magnitudes for all point sources in the image. This allows us to compare to known values. It will also include any unknown point sources.

As a user, I want to see a list of light curves that I've created

A page that lists & links to light curves created by the current user.

A link to this page can go in the nav bar for internal pages.

As a user, I want to view a list of all my LightCurves

Users should have a navigation option to see a list of LightCurve objects that they created. Each item in the list should link to a lightcurve page.

A link to this page can go in the nav bar for internal pages.

Give more detail on photometry

• Export the mean, median, std of sigma_clipped_stats
• Export other starfind output, such as peaks?
• Make fwhm and threshold adjustable by user?

See #47

As a user, I want to see the status of each image in my Lightcurve

Each image either needs review or is reviewed (meaning reduction has run)

As a lightcurve creator, I want to rename my light curve

Currently lightcurve names follow a preset format, "username YYYY-MM-DD". User should be able to rename this light curve on the light curve page. Renamed title should display in lists of light curves.

After reduction, there should be "next image" button and an "add to light curve" button

This saves clicking around on the main light curve page

Next image: links to next "pending analysis" image
Add to light curve: changes status of this imageanalysis and links to light curve plot

As a user, I want to create a Lightcurve object from a batch image upload

A batch image upload should lead to a Lightcurve page that lists all the images.

As a reviewer, I need to see a plot of raw instrumental magnitudes over time

This is a sanity check that can immediately show bad data points.

As a admin, I want analysis and reductions to happen automatically

As a user, I want the software to load the image timestamp automatically from FITS data

FITS data will almost always have a timestamp. Load it automatically into ImageAnalysis.image_datetime

Consider doing the same for latlng, elevation, and other metadata if available!

As a careful user, I want to see a linearity test by plotting my magnitudes vs catalog magnitudes

This would help users verify that nothing crazy is going on. We expect the relationship from instrumental to catalog magnitudes to be roughly linear.

This can happen before and after the reduction with instrumental magnitudes and standard magnitudes respectively. The output should include an image and also the correlation.

Two additional linearity tests

• standard mags vs catalog mags
• instrumental mags vs catalog mags (this visualization exists but needs to be improved)

As someone performing reduction, I want to select the image in a different band to form a Color Index

As a user, I want to view results of the astrometry processing of each image.

In the lightcurve view, user can trigger astrometry analysis and then view results.

LightCurve and ImageAnalysis should only be editable by the user that created it

Right now anyone who knows the URL can edit a light curve or ImageAnalysis. Everything on the platform is publicly viewable, but changes should be restricted to the user that created each object.

As a image reviewer, I want to select my target point source

As a scientific user, I want to export my Lightcurve in ALCDEF format.

ALCDEF is a special standard for light curves. It's formatted ASCII text.

See here: http://alcdef.org/docs/ALCDEF_Standard.pdf

As a user, I want to see a plot of the lightcurve based on included images

For all images that the user has run reductions for and included, add it to a lightcurve plot.

Upload page is broken visually

When you upload a large number of files, it looks broken

Also, we should disable the image preview, because FITS files cannot be viewed in browser.

Allow users to group multiple AnalysisResults together into a LightCurve

A LightCurve object is a list of AnalysisResults. The app will have to group a bunch of user results together and display them as a single light curve.

Complete transformation coefficient reduction (Tf)

Compute T_f in the formula for converting instrumental magnitudes to standard magnitudes.

Here's an example: https://www.aavso.org/transformation-coefficients-m67

As a careful user, I want to know the uncertainty of any calculations

All calculations need to be displayed with uncertainty. We need to identify the places where this is not the case and propagate those values to the frontend. 1/SNR is usually a useful uncertainty value.

As an image reviewer, I want to return to light curve at any point during the review process

Each image review flow page should have a 'Return to Light Curve' link

Allow user to specify unknown object of interest

Currently we attempt to compute magnitudes for all objects detected in the image. The user needs a way to designate the object for which they want to compute magnitudes.

As a reduction user, I want to be able to manually enter my target's color index

Some target CIs don't change from night to night, so it is acceptable to just enter a hard value (Warner 119). This color index could be inputted on the reductions page or the main lightcurve page (to apply to all images)

As a user, I want to calculate the hidden transform for all target stars

Break AnalysisResult into parts

Separate observation information (eg. elevation, latlng) from Analysis

As a user, the target should be highlighted in all tables so it's easy to find

Right now it is only highlighted in reduction tables

Separate astrometry step and photometry step

Right now run_astro_phot does both. This makes it harder to debug and forces me to manually edit models when I want to rerun photometry!

As an anonymous user, I want to see a list of ALL light curves created

Make all light curves browseable to people, even if they aren't logged in. Probably makes sense to use the same template as #40?

A link to this page can go in the nav bar for internal pages.

As a user, I want to review instrumental magnitudes for all point sources

This should happen before the reduction flow.
