+* Vertical red line in top panel accompanied by "pixcnt" error message
+
+This means that the frame taken has shifted pixels. You do not need to interrupt observing. Please log 
+the exposure number of the bad frame both in the observing logs and in the bad_expid.txt file.

+* Vertical red line in top panel accompanied by "readtime" error message
+
+This is harmless in general and can be ignored. However, many sequential appearances
+of the readtime error mean that the camera may not be writing new images (as in the first
+case above). In this event, one has to stop observing and restart NOCS.

+May indicate that one has to change to using only pass2 and pass3 or just pass 3.
