Description
obs_cfht is failing on recent CFHT data for 2 independent reasons :
- On old data the keyword "EXTNAME" appears 2 times in the fits header, the first one with the value "COMPRESSED_IMAGE" and the second one with the actual name of the extensions. While on some more recent data (not all !), there is only 1 occurrence of the "EXTNAME" keyword which contains the extension name. Notice that even if COMPRESSED_IMAGE is missing, the image is actually compressed.
- Recent images need new bad pixels mask files. These masks correspond to the addition of 4 more CCD in the focal plane (36-->40).
The first fix is trivial and requires to override the getExtensionName method in ingest.py in order to check whether md.get("EXTNAME") is returning a tuple or a single value.
The second issue requires to get the missing files from CFHT/Megacam (I got them from Jean-Charles Cuillandre) and to convert them in the format expected by obs_cfht. I already did that a few years ago and need to retrieve the method...
New filters have also been installed since period 2015A and should be defined in ingest.py
