caractéristique qhy9

[a722 0]

Salut,
Sur le forum de qhy j'ai posté un message pour avoir des infos sur les caractéristiques de la qhy9. Terry Lovejoy a mesuré les caractéristiques de la sienne et ça donne ça :
Test Software Ascom Driver 1.0.0.10/CCDCap 2.50B unless otherwise noted
Gain at 0% Setting 0.62 e-/ADU
Gain at 100% Setting 0.13 e-/ADU
Read Noise 8.5 e- RMS (overscan - measured in EZCAP1.3)
11 e- RMS (Active Sensor, maximum gain)
12 e- RMS (Active Sensor, minimum gain)
Readout Banding 1.3e- Peak to Peak (2% readout noise)**
Dark Current 0.09 e-/pixel/sec @ 5C
0.01 e-/pixel/second @ -10C
22 hotpixels @ 5C
8 hotpixels @ -10C
2 hotpixels @ -25C
Linearity Excellent (refer graph)
* From examining actual images in EZCap
** Some minor horizontal banding was noticed in highly stretched dark frames
*** Based on pixels that have attained a value of 25,500 e- (point at which signal becomes non-linear)
