All changes to the Metis L1 pipeline are documented in this file.
## 3.1 - 2022-01-27
- Manage the new format of the VL bad-pixel map which now includes the detector reference rows.
- Fix a bug that caused wrong values in the WCS keywords CTYPE1 and CTYPE2 of UV images.
- Add management of errors originating from the lack of a mandatory parameter in the input HK table: the pipeline now exits with a non-zero error code.
- Add management of the predictive Solar Orbiter’s SPICE meta-kernel.
- Duplicate some Metis specific WCS keywords in the FITS header using more user-friendly names:
- SUNPIX1 = SUN_XCEN and SUNPIX2 = SUN_YCEN
- SCPIX1 = SC_XCEN and SCPIX2 = SC_YCEN
- IOPIX1 = IO_XCEN and IOPIX2 = IO_YCEN
- FSPIX1 = FS_XCEN and FSPIX2 = FS_YCEN
- Optimize the solo_get_pointing.pro routine in order to also provide coordinates of the spacecraft in the celestial J2000 coordinate frame.
- Fix a potential bug in the make_bin_table.pro routine.
- Make changes to better handle the L0 FITS files generated from the new version of Metis OBSW 2.2.0.
## 3.0 - 2021-07-19
- Modify the pipeline to manage the new input I/F which includes the full set of Solar Orbiter SPICE kernels and the Metis Calibration Package. In the input file contents.json, the two fields TLS_FILE_NAME and TSC_FILE_NAME are now replaced by the field SPICE_KERNELS providing the path of the Solar Orbiter SPICE kernels folder. The field CAL_PACK_PATH is added to provide the path of the Metis Calibration Package folder.
- Add the WCS (World Coordinate System) keywords to the FITS header and a set of routines to perform calculation of the instrument boresight parameters and S/C coordinates.
