ASIAIR Beta v2.2 firmware 11.19 (payload of ASIAIR app build 62) looks good.
This is a single bias frame (1ms) at gain 0 for my copy of the ASI585MC "Pro":
This is a 60sec dark frame at gain 0:
This is bias frame right at HCG (gain 25.2 dB):
and this is a 60 sec dark frame at the same HCG:
In all cases, the Min ADU is well over 0, unlike my post #5 on this thread.
Notice that for 60 seconds at HCG and -10ºC, the dark current noise is close to the read noise. From the last two images, the RMS read noise is about 54 ADU, while the RMS read noise + dark current (thermal) noise is about 84 ADU. If thermal noise at 60 seconds were equal to the read noise, the second RMS noise would have come in at 54*sqrt(2) = 76 ADU.
Looks like I can start using this camera again (once the clouds clear :-). It was just too noisy when I was testing it earlier, with the wrong camera offset, that I had mothballed the 585, and went back to my larger pixel cameras.
