==================

- Image EDR SRU_1_2022015T120017_39_V01.FIT from orbit 39 is missing 89 
	rows (lines) of data. This was due to a ground data system issue.

- Image EDRs SRU_1_2022272T153032_45_V01.FIT, SRU_1_2022272T165602_45_V01.FIT,
	SRU_1_2022272T150031_45_V01.FIT and SRU_1_2022272T171432_45_V01.FIT from 
	orbit 45 are corrupt from straylight contamination due to a spacecraft 
	attitude adjustment that disallowed controlled pointing during SRU 
	imaging.

- The first row of data of Image EDR SRU_1_2022272T093649_45_V01.FIT from 
	orbit 45 contains corrupt values.

- Users of data from orbit 47 should take note that an on-board mass memory 
	event resulted in significant corruption and loss of data from this 
	orbit. The following Image EDRs each contain some pixels with 
	nonsensically high values (>37,000 DN):
		SRU_1_2022348T150021_47_V01.FIT
		SRU_1_2022348T160013_47_V01.FIT
		SRU_1_2022348T170005_47_V01.FIT
		SRU_1_2022348T180028_47_V01.FIT
		SRU_1_2022348T190021_47_V01.FIT
		SRU_1_2022348T200013_47_V01.FIT
		SRU_1_2022348T210005_47_V01.FIT
		SRU_1_2022348T220028_47_V01.FIT
		SRU_1_2022348T231812_47_V01.FIT
		SRU_1_2022349T000013_47_V01.FIT
		SRU_1_2022349T024013_47_V01.FIT
		SRU_1_2022349T033003_47_V01.FIT
		SRU_1_2022349T034815_47_V01.FIT
		SRU_1_2022349T040533_47_V01.FIT
		SRU_1_2022349T042243_47_V01.FIT
		SRU_1_2022349T045427_47_V01.FIT
	Image EDR SRU_1_2022349T043922_47_V01.FIT contains 357 nonsensically 
	high pixel values, two 6-row gaps of missing data, and some 
	nonsensically low pixel values. 

- Image SRU_1_2023212T073007_53_V01.FIT from orbit 53 has two 6-row gaps of
	missing data.

- Images SRU_1_2023212T040407_53_V01.FIT and SRU_1_2023212T044458_53_V01.FIT 
	from orbit 53 have stray light corruption.

- These images from orbit 55 have stray light corruption:
	SRU_1_2023288T055525_55_V01.FIT
	SRU_1_2023288T063032_55_V01.FIT
	SRU_1_2023288T070450_55_V01.FIT
	SRU_1_2023288T074057_55_V01.FIT

- Image SRU_1_2023288T083016_55_V01.FIT from orbit 55 has a 6-row gap of missing data due to corruption on-board the spacecraft.

- Image SRU_1_2023326T130312_56_V01.FIT from orbit 56 has a 6-row gap of missing data due to corruption on-board the spacecraft.

- Image SRU_1_2024100T020011_60_V01.FIT from orbit 60 contains saturated pixels due to the presence of Callisto in the field of view.

- Image SRU_1_2024165T100027_62_V01.FIT from orbit 62 has a 6-row gap of missing data due to a data corruption event.

- Image SRU_1_2024165T150016_62_V01.FIT from orbit 62 has a 6-row gap of missing data due to a data corruption event.

- Users of data from orbit 66 should take note that (due to onboard data corruption events) the following four images each contain
	several	pixels with corrupted signal values that are anomalously high relative to the local background level:
		SRU_1_2024296T143015_66_V01.FIT
		SRU_1_2024296T154903_66_V01.FIT
		SRU_1_2024296T180419_66_V01.FIT
		SRU_1_2024296T182617_66_V01.FIT

- Image SRU_1_2025028T234959_69_V01.FIT from orbit 69 has two 12-row gaps of missing data due to a data corruption event.
