PROCEDURE: swe_a0_snap PURPOSE: Plots 3D snapshots in a separate window for times selected with the cursor in a tplot window. Hold down the left mouse button and slide for a movie effect. If housekeeping data exist (almost always the case), then they are displayed as text in a small separate window. USAGE: swe_3d_snap INPUTS: KEYWORDS: LAYOUT: A named variable to specify window layouts. 0 --> Default. No fixed window positions. 1 --> Macbook Air with Dell 1920x1200 external screen. 2 --> HP Z220 with twin Dell 1920x1200 screens. 3 --> Dell 2009W 1680x1050 with Macbook Air This puts up snapshot windows in convenient, non-overlapping locations, depending on display hardware. MODEL: Plot a model of the 3D data product with the test pulser on in a separate window. (An analytic approximation to the test pulser signal is used. See 'swe_testpulser_model.pro' for details.) KEEPWINS: If set, then don't close the snapshot window(s) on exit. ZRANGE: Sets color scale range. Default = [1,3000]. ZLOG: Sets log color scaling. Default = 1.
