What about oversampling?
Posted: Sat Oct 15, 2011 9:58 am
The question raised by Stephane Charbonnel (binning 3X3) leads me to raise the opposite question: what about oversampling? I have had this question in mind for a long time but never found the opportunity to raise it. With my question, I do not mean the situation where the pixel size is small compared with the slit width (the converse of the situation described by Stephane). I mean the following: I make extensive use of interpolation in my processing algorithms. This may lead me submit to Bess a profile with, for instance, 5000 samples whereas my CCD Chip is 1000 pixel wide. I could of course convert (by interpolation) my 5000 sample profile so as to match the CCD characteristics but I suspect this conversion to degade the result.
Can we envisage to submit to Bess profiles involving much more samples than there is in the CCD chip?
