Spending that amount of time gathering imaging data is one thing, and that's huge. But the amount of work you've put into the supplemental information and writeup - to a noob like me - that looks like a PhD submission! The combination of both is absolutely monumental. Hard to believe, but you've exceeded your previous attempts by a mile. I have no idea where you can go from here, but looking forward to it!
PS - I'm off to read more on intracluster light. I'm familiar with IFN etc, but not IcL.
PPS - I'm interested to know more about the data acquisition philosophy on such a huge amount of data on a night by night basis. You mention 4-5hrs data collected each night, but it's hard to tell from your graph whether you'd do all L in one night, all R in another night etc, or if you gather less subs of all LRGB in the same night?
