Could you add spectral response function for GCOM-C/SGLI sensor ?

Hi!
It would be great to have GCOM-C SGLI added, indeed. I am not familiar with the instrument and do not currently work with the data, so I think it would be faster and better if you started implementing the support in Pyspectral. I will gladly try helping you!
I found RSR data here:

There are also the 3-telescope data. I am not sure what that means, but I see that the instrument can scan in +-45 degrees?

I will let you judge how ambitious we should be in adding support for SGLI, and how to possibly treat the three telescopes in a general way.

You could have a look at #144 to see how to start. Then once you have a reader for the original responses you can generated the hdf5 files and send me, or I can generate them here, and then upload to Zenodo.

Hi, thank you for your quick response. I think, providing RSR only for Nadir (N) telescope should be enough.

All-band RSR (low resolution)

Then, umm, it may be the same way you provided RSR for other sensors like MODIS....

Good. Yeah, it should be fairly straight forward, and re-using the function to write hdf5, so basically it is only making a reader for the new data. Tell me if you start on something. Otherwise I will do it, but can't promise a schedule for this yet.
