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

SVC gains for Polymer 4.10 and 4.13
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

Re: No-data values in Polymer Level2
Hi François, Sorry that you ended up replying the same thing twice - just saw the email. In a match-up work for British Columbia waters, I observed that this flag perfectly indicate pixels where the Chl-a retrievals failed. Removing those pixels, which are not that many, the statistical performance ...

Re: No-data values in Polymer Level2
Hi François Thank you for your reply. Yes, I thought of removing line 111 from Level2.py. I will give it a try. If you dont mind, I will try to explain in more details what I am doing, so maybe you have a clue. Usually in the mosaic script I set a couple of "conditions" to exclude pixels that I want...

Re: No-data values in Polymer Level2
Hi François No problem. Thank you I actually found a discussion in that forum and it seems the problem is the way that the original files to be mosaiced have their "no-data" set up. For example, instead of NaN, the netcdf files have No-data as a generic number 9.969E36. However, the GUI is able to c...

No-data values in Polymer Level2
Hi I am trying to use the gpt-snap tool to run a mosaic operator on polymer products. However I am having a problem to use the following expression: if bit_set(bitmask,10) then NaN else logchl It works perfectly in the SNAP GUI interface, but in the gpt-snap, the final netcdf turn 'NaN' into '0.0000...
