FORS2 IMG: ZERO POINTS (long term trending)

Postscript version available here
zero points of photometric nights 2006-09-03 to 2006-12-03 CHIP1 CHIP2 Filter zero point range frames zero point range frames U 24.15 +/- 0.05 24.08 ... 24.26 16 24.25 +/- 0.07 24.10 ... 24.35 12 B 27.62 +/- 0.04 27.58 ... 27.71 16 27.63 +/- 0.05 27.59 ... 27.77 14 V 28.10 +/- 0.05 27.96 ... 28.14 17 28.12 +/- 0.03 28.04 ... 28.16 14 R 28.35 +/- 0.07 28.15 ... 28.42 17 28.35 +/- 0.02 28.33 ... 28.40 14 I 27.69 +/- 0.04 27.55 ... 27.72 18 27.71 +/- 0.03 27.64 ... 27.76 16 avg. zero point average of the zero points per frame of all photometric nights, weighted by their inverse error range range of zero points observed in the photometric nights frames total number of frames from photometric nights For daily FORS2 health check, focus on: boxes per standard filter (BVI_BESSELL, UR_Special): The DFO generated zeropoints (black) come per frame, with errorbars. Blue are the values generated by the quick-look pipeline on Paranal, one value per pointing. There may be several entries per night. Values are generated for both CHIP1 (upper row) and CHIP2, 2x2 binning only. Blue points come from pipeline log files transferred daily by PSO. Other points are from regular QC processing at Garching.
