Steve:
I know this is something that Dave Herald has been pushing for, and to date I haven't looked into it much. Wish I could help on the procedure, but I don't know it.
However.... ever since PyMovie/PyOTE came out I have been including a screenshot of my light curve(s) with my report anyway - so a light curve will always be available for my observation.
That said, it's my feeling that supplying just the sole light curve of my Target Star is "worthless" -- without including the light curve of at least one Comparison Star near the Target. The inclusion of a Comparison Star , I feel, notably adds "validity" to the claimed event.
In PyMovie you can display both the plots of the Target Star and a "Composite Plot" [Target Star, Comparison Star(s), Background Measurement]. I "stack" them and then do a screen capture (Windows Key + Shift + S). I'll often "expand the Target Star plot a bit also.
Below is a sample using an occultation I captured last night (July 2 UT).
I really do feel at least 1 Comparison Star should (/must) be included in any light curve that is submitted -- but that's my 2-cents.
