PROCEDURE: swe_pad_snap PURPOSE: Plots PAD 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. A PAD snapshot is an pitch angle X energy spectrogram at the selected time. Optionally, keyword ENERGY can be used to plot a PAD in histogram mode for a single energy. USAGE: swe_pad_snap INPUTS: KEYWORDS: ENERGY: Energy (eV) to use for the histogram plot. UNITS: Plot PAD data in these units. PAD: Named variable to hold a PAD structure at the last time selected. DDD: If set, compare with the nearest 3D spectrum. SUM: If set, use cursor to specify time ranges for averaging. SMO: Number of energy bins to smooth over. LABEL: If set, label the anode and deflection bin numbers. KEEPWINS: If set, then don't close the snapshot window(s) on exit. ARCHIVE: If set, show snapshots of archive data. DIR: If set, show some useful information with respect to the observed vector magnetic field in the MSO and LGEO(local geographic coordinate). $LastChangedBy: hara $ $LastChangedDate: 2014-11-26 12:02:05 -0800 (Wed, 26 Nov 2014) $ $LastChangedRevision: 16312 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/maven/swea/swe_pad_snap.pro $ CREATED BY: David L.
