Atik Titan – Gain and Read Noise Analysis

This is an analysis of gain and read noise of the CCD Atik Titan.
I used as samples, two bias frame and two photos of M27 taken with 60 seconds of exposure, even though it should be done with flat frames, as said in my documentation, probably because they have a better signal to noise ratio.

Anyway the result are in line with the official website specification so I am more than satisfied.

Here you can download the sample images I used.

STD Mean Pixel Atik Titan Specification
Bias1 21,04 1235,00
Bias2 20,95 1235,00 FWC (e-) 22500,00
Flat1 468,87 11883,83 ADC (bit) 16,00
Flat2 492,62 11798,47 Readout Noise (e-) 7,00
  FWC (e-/ADU) 2,91
Mean (Bias1 + Bias2) 2470,00
Mean (Flat1 + Flat2) 23682,30
 
STD (flat1 – flat2) 419,72
STD (bias1 – bias2) 29,51
Gain (ADU) 0,12
Gain (e-/ADU) 0,35 Gain Factor (e-/ADU) 0,34
Read Noise 2,53 Readout Noise (ADU) 2,40
