Update astrometric imaging pipeline and add calibration data
As discussed in #116 (closed) and in our meeting, add the following data:
-
REF_WAM_CAT
with the reference position of the pinholes. -
WAM_RAW
with an observation of the warm astrometric mask. Using different rotation angles. - (
WAM_CAT
with the measured positions of the pinholes. This is probably not necessary as it is used only internally.) -
DISTORTIONWAM_HDR
with the distortion (polynomial coefficients) as derived from theWAM_RAW
. -
STDFIELDASTROM_RAW
with an observation of a standard astrometric reference field. -
DISTORTIONELT_HDR
with dispersion of the rest of the ELT.
The AI pipeline should have the following output:
- A catalog, not a stack, with measured and corrected positions.
- Distortion corrected images where the distortion correction is applied to the pixels.
The following data items are removed:
-
PSM*_CAT
, these are replaced byDISTORTIONWAM_HDR
andDISTORTIONELT_HDR
.
The difference between standard imaging and astrometric imaging is:
- In astrometric imaging a distortion is fit per exposure, where in standard imaging the same one is used for every exposure in the same OB.
- Only the 3 guide stars are used with standard imaging, where with astrometric imaging many more stars will be used.
