New flats for Pier 5 have just been uploaded Calibration Frames - Pier 5 Flats (roboscopes.com)
These are labelled Lum and OSC. Since it is a colour camera I am not sure which these refer to. Is the OSC set connected to the new RGB filter which was to be installed, and the LUM set an update to the flats we were having gradient problems with?
Can anyone clarify?
