Hi,
I have a question regarding the SVC gains. Are the SVC gains applied in version 4.10 and 4.13 the same?
According to the "release notes" of v 4.12, the SVC would have been updated, but I wonder if they were only applied back, as in version 4.11 they were set to 'zero'.
Thank you a lot

Hi Fernanda,
The SVC gains are not the same in v4.10 and v4.13. They are defined in params.py, see self.calib in method defaults_olci.
For your information, they have been reset to 1 because of an algorithm change in 4.11 which would make them inappropriate, then re-calculated with this algorithmic change and re-introduced in 4.12.
Cheers,
François

Thank you Francois,
So, the coefficients are different due to the algorithm update, but not an update in the SVC. Is that correct?
Thank you

Yes indeed, the SVC update follows an update of the algorithm.
Cheers,
