I am using a Sony A7Riv camera with (somewhat beta) ASCOM drivers.
If I load a raw ARW file into Pixinsight, it thinks the dimensions (before debayer) are 9568 x 6376.
If I capture a file as FIT in APT using the driver the size is 9600 x 6376 (I also did some debug runs and the size is coming from the driver not APT).
I found this after I spent about a day building Bias and Dark libraries using raw (because it was easier and faster) and then went to integrate with flats taken with APT and ... geometry mismatch.
Obviously I can decide to use one or the other exclusively but... Which one is right?
(This may seem like a simple question of looking up the sensor size, but ever spec I can find only lists it after debayer at 9504 x 6336).

PS. I've asked the driver developer also, but that Pixinsight is finding a smaller number I'm more suspicious the problem is there. Note also the height is the same in both.
