Ok listen,
The "spots" seen last night are *not* bad pixels, they are not always
present (I've seen them on 2-3 occasions myself), they occur as a group of
perhaps 4 or 5 blobs along the x axis (i.e. aligned with the normal bias
patterns) near the top of the chip (IRAF), they are much wider than typical
stars in bad seeing, they are not exactly the same shape or brightness, but
are similar in form and are spaced semi-regularly along the x axis, they are
*not* burn in, as A). Grim hasn't seen another star of ANY brightness in well
over a week, B) I have nailed the GRIM with 0th mag stars before and NEVER
seen any residual even in the very next image let alone in a series of 20 or
more. I have no idea what they are. Please do not take second-hand quotes
from other sources and pretend they are the gospel truth.
Speculation will get us nowhere.
