RUN#1

Characterize CCD Camera
Bias Frame: T:\u42test20051117\20051116domeflatLEDccd-085bias.fit
Flat-Dark Frame: T:\u42test20051117\20051116domeflatLEDccd-085dark120s.fit
Flat Frame #1: T:\u42test20051117\20051116domeflatLEDccd-084r.fit
Flat Frame #2: T:\u42test20051117\20051116domeflatLEDccd-083r.fit
Conversion Factor = 1.00 electrons/ADU = Gain
Readout Noise = 5.65 electrons RMS

RUN#2

Characterize CCD Camera
Bias Frame: T:\u42test20051117\20051116domeflatLEDccd-085bias.fit
Flat-Dark Frame: T:\u42test20051117\20051116domeflatLEDccd-085dark120s.fit
Flat Frame #1: T:\u42test20051117\20051116domeflatLEDccd-080r.fit
Flat Frame #2: T:\u42test20051117\20051116domeflatLEDccd-081r.fit
Conversion Factor = 0.98 electrons/ADU
Readout Noise = 5.53 electrons RMS

PS. 和最初原廠測試資料 (Gain = 1.5 electrons/ADU, Readout Noise = 12 electrons RMS) 不同!?

U42經過一年來送送修修,目前總算比較正常了!

下為 U42+RCOS16+No filter 拍的星場,左邊星像很好,右邊卻不正常(焦平面不正?RC像差?)

Still problem after Bias/Dark/Flat reduction.

Vignette problem on top side of  U42 CCD image (Y=0~100), change the U42 orientation is of no use.
