Star label missing

Hi!

I'm trying to get an A4 chart of Gemini per the included example.

It works fine up to angular_width=22.2. When I push it to 22.3 or beyond, Castor's label disappears.

Fiddling with the center of the chart or font_size may bring it back in some cases, but it's finicky.

Am I missing some configuration tweak?

Regards,

L

alt_az cardinals are misaligned.

The "E" and "W" cardinal direction labels in the alt_az chart are not aligned vertically. I believe the label_positions should be as follows:

            chart_label(p, s, black, "N",
                        &(label_position) {-dh * sin(a), -dv * cos(a), 0, 0, -1}, 1,
                        0, 0, 2.5, 1, 0, 0, -1);
            chart_label(p, s, black, "E",
                        &(label_position) {-dh * sin(a + DEG90), -dv * cos(a + DEG90), 0, 1, 0}, 1,
                        0, 0, 2.5, 1, 0, 0, -1);
            chart_label(p, s, black, "S",
                        &(label_position) {-dh * sin(a + DEG180), -dv * cos(a + DEG180), 0, 0, 1}, 1,
                        0, 0, 2.5, 1, 0, 0, -1);
            chart_label(p, s, black, "W",
                        &(label_position) {-dh * sin(a + DEG270), -dv * cos(a + DEG270), 0, -1, 0}, 1,
                        0, 0, 2.5, 1, 0, 0, -1);

Compiling Error - unsupported option - 'fopenmp'

Each time I run the setup shell there is a compiling code error at the same place during producing output data catalogues.

application crashes running orion.sch example

After installing star-charter running under Ubuntu in VirtualBox the first example run was the orion.sch example provided. The code quickly crashed with the following errors after running the command

../bin/starchart.bin orion.sch

Add manmade objects to charts

Would you be interested in a PR to add man-made satellites to your charts?

It's relatively straightforward to get the TLEs for satellites, then use that to compute the pass.

Stick Width attribute absent

From README the constellation stick width attribute is absent.

Ephemeris tool doesn't find bound_20.dat

Running ephem.bin raises a file not found error relating to bound_20,dat.

Braille compatible command line output

Is it possible for a contributor to add a mode that outputs the data to the command line in a way that can be panned around?

I'm from Bristol Braille and we and a Braillist are working on creating a fully tactile map of the night sky. We will be using the Canute Console which is a 40 cell by 9 line tactile output which precisely mirrors the terminal output. If star-docker could output directly to the command line, and be panned around from the command line, then the Canutr Console's built in conversion will do the rest and that will create one of the first fully spacial and digital tactile maps of the night sky for blind people.

README file : Date range for solar system objects

I think it would be useful to mention in the README file that there is a date cutoff when requiring the paths of solar system objects.

The cutoff dates are mentionned in the ephemerisCompute repository but I think a reminder in the star-charter project would be informative, maybe providing the actual JD range that is OK to use.

I tried plotting paths outside of that range and got unexpected results. The program could also log a warning in this case so users know about it.

Error: Could not open Tycho ASCII catalogue

I downloaded the package, installed the dependencies, also downloaded the new versions of empty star database (ftp://cdsarc.u-strasbg.fr/pub/cats/I/239/hip_main.dat). The catalogue merge script exits:

(...)

I see the following error during the program run using sample data:

Please advise, thank you!

Tiles missing from field of view

It seems like some of the tiles are being excluded from the field of view. I've attached a parameter file where this effect is visible. There is a fairly clear cutoff of faint stars above Orion's belt
wide.txt
.
For now I've worked around the issue by commenting out both uses of test_if_title_in_field_of_view() in astroGraphics/stars.c.

broken link on referring website

Amazing tool! I just wanted to let you know that the referring website (https://in-the-sky.org/data/constellations_map.php) links to this page as https://https//github.com/dcf21/star-charter with an extra https.

Fatal Error src/astroGraphics/stars.c at line 87

Fresh installs with setup.sh in Docker result in the following error:

Error: Fatal Error encounted in src/astroGraphics/stars.c at line 87:
Error: Could not open Tycho ASCII catalogue

Note that this is even after correcting for the broken file link issue as recommended by @jackschmidt in #4 (comment)
