SuSI2: Photometric Zero Points


The following figure displays the evolution of the count rates and zero points (in electron/s, atmosphere corrected). Significant events have been indicated as labels. This page is generated automatically. The photometric reduction is performed using the Tmag Midas package.

The two chips of SuSI are very similar; these Zero Points are the average for the 2 chips.

Detector Set-Up: Fast, bin 2x2
Counts: 10^4 e-/sec, airmass=0, M=15
Zero Points: adu, airmass=0

ls-susi: updtate procedure in SciOps www: ~/Photometry/susiZP/README

The archive of photometric solutions is available as an ascii file. These are obtained on the raw frames, i.e. they should be used only on frames flatfielded with a flatfield globally normalized to 1.

Zero Points of other imagers: EMMI, SUSI2, EFOSC2, WFI.
