Lines on Atik Darks

[Davey-T]

Just done new set of calibration frames with Atik 314L+ and four of the dark frames have white horizontal lines in various places.

Any ideas as to the cause ?

Are they the same on all the frames?

I thought the norm for CCD errors was vertical lines. Probably some sort of noise in the USB cable.

Different places up and down but all horizontal. Thought it might be cable related, just wondered if anyone else had seen it.

I've never seen that effect but USBs are the root of most CCD evil.
