#241 En masse datapoint exclusions/inclusions

David Benn

Doug Welch suggested the following via email (excerpts from original text):

1. Group exclusions: In the "Observation Plot" window, with either raw or phased data, being able to select points with a rectangle and then right-click (or something) to exclude all of them. (Possibly with the option to continue to plot the excluded points with a different symbol or colour. If so, you could re-include those points in a similar way.)

2. Same but in the "Observation List" window but being able to select a whole range of rows at once for exclusion or re-inclusion.

One motivation for this is, in Doug's words: "In the SuperWASP data whole nights seem to be bad sometimes and since they acquire LOTS on points in a single night, checking boxes can be time-consuming!"

My initial thoughts to Doug were that seems like a very useful thing to do. We already have a series that is set aside for such excluded data points. Here are my preliminary thoughts:

o We could have menu items and toolbar buttons specifically for exclusion/inclusion.
o Any data selected via list rows or plots would be affected by these.
o Rather (or as well as?) than selecting via a bounding box on a plot, would it make sense to permit exclusion/inclusion of filtered data? (e.g. search for all data with mag in a range)

    Another comment from Doug (Dec 26): "One of the issues is that there may be several groups that you want to do sequentially and you'd want the option of doing/undoing everything or just some selection."

    Doug likes the toolbar idea, and a range (via filtering) exclusion too.

    I agree that being able to do group exclusions/inclusions would be a useful thing. I would also like to suggest that selecting the observations only via the data filtering method could be very time consuming as compared with being able to do it with a bounding box because in many if not most situations, you would have to specify both the magnitude and the JD range to exclude. This may be my zapper bias speaking, but typing in JDs would be a drag, especially if you can clearly see the observations to exclude and you just want to grab them.

    Thanks for your practical insight Sara. That makes sense. I guess the reason I was thinking of including this capability from within the filtering dialog is for completeness and because it may be useful when the selection criteria are complex.

    Note that one of the problems with "...being able to select points with a rectangle" (Doug's point 1) is that currently, doing so causes a zoom operation to take place. Perhaps we can make use of a key such as control to distinguish zoom from selection?

    We should also establish undoable edits for this.

    In 2.16.8 Filter from Plot was added. A next obvious step would be to added an Edit menu item to Exclude visible Observations in Plot or similar.
