Fig. 4.
Master dark images for two MUSE CCDs, both combined from 149 raw dark images taken between 2018-06-25T11:20:47 and 2018-08-21T06:56:51. The CCD of channel 7 shows broad horizontal stripes, while the CCD of channel 10 shows a noticeable block of hot pixels. The location of the hot corners is different for both CCDs, and while channel 10 shows a vertical gradient seen in most MUSE CCDs, this is less apparent for the CCD in channel 7.
