Hi,
I’ve been working on DP2, searching for light curves of AGN.
I checked known AGN from Boutsia et al. (2009) using the official DP2 tutorial.
Variability-selected AGN in ECDFS from Boutsia et al. (2009)
I found that some sources look very similar or almost identical.
One example is AGN 28 and 29. And even 30.
Here are the light curves I was able to get
Using those IDs and coordinates.
ID 28 RA=53.337875 Dec=-27.653278
ID 29 RA=53.155375 Dec=-28.146389
ID 30 RA=53.302625 Dec=-27.931000
I also checked DiaObject
AGN 28 - DiaObject 755371566388215879
AGN 29 - DiaObject 755369573523390565
AGN 30 - DiaObject 755370191998681178
I was using psfDiffFlux and psfDiffFluxErr.
I was wondering if those values are appropriate to use.
Are those well determined, and if yes, should we use them, or should we rely on something else?
The sources are not close to each other; thus, it is not the same source. However, by examining the data, it looks suspicious, and not sure if that is right.
I would like to hear suggestions or your experience if you used the DP2 data to extract some photometry of AGN and plot light curves.
