Methods for Calibration #5

Open dyerlytle opened 5 years ago

dyerlytle commented 5 years ago

In DeadParrots/Asteroid_Photometry/calibration/steps.md, are the steps correct? What other questions do we need to answer? What packages can we use in Python for this calibration?

astrobokonon commented 5 years ago

Depends; if it's high level, it's ok. If it's supposed to be a much more fine grained recipie, then it's missing stuff like darks, and normalization/converting to DN/sec. For those it varies depending on the instrument since you have to know where to look in the FITS header, or even if darks will help or hurt your end result.

astrobokonon commented 5 years ago

Your bias/overscan question is a good one, since you could in principle use those to double check your bias/darks before applying them.

I wouldn't touch the reprojection/scale issue at this point, someone could give a series of seminars about Montage and flux preservation concerns!
