| | ACS::HRC#1 : Gain, Noise, Linearity, Saturation |
 | | The main goal is to measure the primary system gains of 1, 2, 4 and 8 e-/DN with the photon-transfer method as well as the read noise for each amplifier of the HRC flight build 1 detector. |
 | | A sequence of flat field pairs is acquired at each gain setting, over as wide a range in count levels as possible, from the read-out noise at low levels (usually at the shortest integration time of 0.1 sec), through the linear part of the curve, and up to non-linearities and saturation at the highest levels. |
 | | The system gain (e-/DN) and total noise (e-) of the primary gain settings of 1, 2, 4, and 8 for the HRC build 1 detector were measured. |
