s_calib_status |
Type of calibration along the spatial axis |
1 |
Char.SpatialAxis .calibrationStatus |
uncalibrated, raw, calibrated |
A string to encode the calibration status along the spatial axis (astrometry). Possible values could be {uncalibrated, raw, calibrated} and correspond to the Utype Char.SpatialAxis.calibrationStatus. For some observations, only the pointing position is provided (s_calib_status =”uncalibrated”). Some other may have a raw linear relationship between the pixel coordinates and the world coordinates (s_calib_status = ”raw”). |
t_calib_status |
Type of time coordinate calibration |
0 |
Char.TimeAxis .calibrationStatus |
uncalibrated, calibrated, raw, relative |
This parameter gives the status of time axis calibration. This is especially useful for time series. Possible values are principally {uncalibrated, calibrated, raw, relative}. This may be extended for specific time domain collections. |
em_calib_status |
Type of spectral coord calibration |
0 |
Char.SpectralAxis .calibrationStatus |
uncalibrated, calibrated, relative, absolute |
This attribute of the spectral axis indicates the status of the data in terms of spectral calibration. Possible values are defined in the Characterisation Data Model and belong to {uncalibrated, calibrated, relative, absolute}. |
o_calib_status |
Type of calibration for the observable coordinate |
1 |
Char.ObservableAxis .calibrationStatus |
absolute, relative, normalized, any |
This describes the calibration applied on the Flux observed (or other observable quantity). It is a string to be selected in {absolute, relative, normalized, any} as defined in the SSA specification (Tody, Dolensky and al. 2012) in section 4.1.2.10. This list can be extended or updated for instance using an extension mechanism similar to the definition of new UCDs in the IVOA process, following the feedback from implementations of ObsTAP services. |
