Failures in spiceinit do not pass along detailed error message produced by the camera models.
When spiceinit runs and fails it does not output the detailed error messages generated inside the camera models.
Steps to reproduce:
Run the category test for cassini ISS NA "issnacam". The error message from spiceinit on the third test is:
ERROR Unable to initialize camera model
and the error added to the output kernels group is:
Can not find [INS-82360_P0_MT2_FOCAL_LENGTH] in text kernels
These are helpful additions, but the cassini iss na cammera model throws:
Unable to find a focal length for the requested Cassini ISS NA
filter combination [xxxx] or the default focal length INS-82360_DEFAULT_FOCAL_LENGTH
