Creating colour images from non-RGB broadband filters
« on: 2017 October 25 16:55:27 »
Does anybody have experience that they would be willing to share about creating colour images from broadband filters other than the typical R/G/B ones, e.g. from SDSS data?  I have some thoughts on how to do this but would be happy to not to reinvent wheels if there is some expertise on the forum that I can tap.  Pointers to useful info would also be appreciated.

Thanks,
Rick.

If I understand you correctly, this thread came to mind:

That what you mean?

Thanks for drawing my attention to that thread, Troy.  I think that Juan's script will be interesting reading.

Cheers,
Rick.

After the forum thread mentioned by Troy, Vicent and I wrote a small tutorial where we describe in detail the method of color filter synthesis we used for the Alhambra survey:

Let me know if you need more information or help to implement something like this.
