I looked at the SPCC data in the repository, and can find sensor data for the Canon EOS 60D, but not for the EOS 60Da which has (AFAIK) a different spectral response.
Sad to say that AFAICT the camera only identifies itself in the CR2 file as an EOS 60D.
Two questions:
Would it be possible to override the camera sensor ID to tell Siril that it is a 60Da?
Can the spectral response for the 60Da be included in the database?
