Hi,
I was trying to use notebook examples to retrieve the data.
I would like to follow up on the conversation we started: DP2 photometry for AGN, which has some
The question is how do you usually treat the data and trust the photometry?
Rather than reliably recording the intrinsic variations of AGN, these light curves are showing some systematic errors in the photometric extraction, I am not sure how you usually treat and deal with them.
Are you also extracting light curves from some nearby comparison stars to check how the comparison stars behave and which one was used as a comparison star for a given AGN?
I would appreciate comments on extraction, reliable photometry, uncertainties, etc.
