Abstract:
In this paper, we present the instrumental characterization and performance of the 4k 4k CCD detector
mounted on a 104-cm Sampurnanand telescope located at ARIES, Manora Peak Nainital, India. A detailed
description of the ¯lter wheel and its motion is presented. We measured the gain and read-out noise along
with the linearity of the detector. Gain estimates are 5–10% higher than manufacturer values. The esti mated read-out noise values do not fall within the manufacturer's range. It is expected that experimentally
derived values will be more precise than designed values. It is suggested that the current derived values will
be used rather than the designed values. The response to the incident light on the detector is linear to 99%
level. To study the performance of a 4k 4k CCD camera, we observe an open cluster Czernik 43. The
fundamental parameters, i.e. log(age), distance and reddening EðB V Þ are estimated as 7.9, 2.5 kpc and
0.65 mag, respectively. The estimated parameters of the cluster are comparable to the values derived in the
literature within the error. Our detailed analysis illustrates that the detector is precise enough to carry out
routine astronomical observations.
