Dark frame measurement of GE1650


(measured by H.Watanabe on 13th Mar. 2007)


* A/D: 12 bit, BIN: 2x2, Exposure time: 80 ms, Frame Rate: 12 Hz, Gain: 0
* Continuous 16 frames were grabbed in 13 times at every 10 min.
* Total duration is 120 min.
* So, the number of all frames is 16x13 = 208 frames.
* Error bars stand for RMS of all pixels of the CCD-chip,
  that we consider the typical level of the readout-noise.
