Trending plots for standard polar field zeropoints: u_g_r_i_SDSS filter.

QC parameters are derived from each of 32 detectors of OmegaCAM STD,ZEROPOINT frames.

DB Name: omegacam_std
Fits header: QC.ZEROPOINT_ELECTRON
QC1 DB: qc_zeropoint_electron

Description:
The zeropoints are measured using flux units in electrons and are contained in the pipeline product frame ZEROPOINTS

Setup:
INS.FILT1.NAME / BIN.X / BIN.Y / READ.MODE / READ.SPEED = u_g_r_i_SDSS/1/1/normal/normal

These Health Check plots describe:
Fig. 1 Zpt_i: Zeropoints from the "i" segment of the composite filter u_g_r_i_SDSS. It is the upper-left quadrant (detectors #81, #82, #83, #84, #89, #90, #91, #92) of the OmegaCAM field-of-view.
Fig. 2 Zpt_u: Zeropoints from the "u" segment of the composite filter u_g_r_i_SDSS. It is the upper-right quadrant (detectors #85, #86, #87, #88, #93, #94, #95, #96) of the OmegaCAM field-of-view.
Fig. 3 Zpt_r: Zeropoints from the "r" segment of the composite filter u_g_r_i_SDSS. It is the lower-left quadrant (detectors #65, #66, #67, #68, #73, #74, #75, #76) of the OmegaCAM field-of-view.
Fig. 4 Zpt_g: Zeropoints from the "g" segment of the composite filter u_g_r_i_SDSS. It is the lower-right quadrant (detectors #69, #70, #71, #72, #77, #78, #79, #80) of the OmegaCAM field-of-view.
