Software
• Level0 to 1 software creates CDF files of the data. Data decompressed, but not calibrated.
• ReadCdf– Simple program to create tab-delimited ascii files of plastic
data
• ScienceOverview– Program to create a series of displays of all the science
data, averaged over a given time period.
• SPLAT (Stereo PLastic Analysis Tool)– Program to plot data versus time, based on the IDL-based
tplot software from Berkeley

Output from science_overview
• Select time period (default 1 day)• Select energy-per-charge range (default all)• Creates a variety of plots averaged over the
time period– Raw event data– On-board classified rates
