LMS Troubleshooting tips
Problems loading images in SkyCat
- Check that you are running the latest version of the OT.
- If a FITS image was used to generate the mask, check that the WCS if that FITS image is correct. SkyCat and LMS rely on the WCS header information while the OT does not.
- Curved slits are not supported at this time by the OT, although should be included soon. Check release notes if to see if this is available function or there are known bugs. Contact email@example.com and we will investigate!
Masks made with Panstarrs images have been found to cause problems. The issue is that Panstarrs uses non-standard astrometric header keywords. This can apeear as a mirror flip in X or slits appearing progressively offset from targets when masks are overlaid on other images (DSS, SDSS, 2MASS, etc) or on-sky when data are taken. SOLUTIONS: 1) Recompute the Panstarrs astrometry using standard keyword headers (more info on Panstarrs header keyword issues can be found here; 2) Once the masks are finished and saved, restart MMS, load a DSS image and save the images again. If using Panstarrs you may wish to contact firstname.lastname@example.org before the deadline to discuss how to handle the situation.
