Description

PaPCo is IDL software for data visualization and analysis. It is modular, PaPCo modules built by various institutions and individuals plug into PaPCo core to provide data products. These modules provide graphic panels that are stacked on a time axis. About 60 modules exist, and 30 are supported as "core modules" that come with PaPCo. There are modules from 15+ spacecraft, including CRRES, Polar, Cassini and Cluster. Data from CDAWeb is plottable as well. The software is open-source, making it very flexible and well-suited for science use.

Caveats
On December 8, 1998 the TIMAS instrument had a high voltage breakdown that resulted in a loss of sensitivity at energies above 700 eV/q and non linear response to ion fluxes at energies below 700 eV/q. The data from the two lowest energy channels in this data set (430 and 585 eV respectively) should be used with caution. Prior to the breakdown, the TIMAS H0 data product provides higher time resolution data in the full energy and angular range. The K1 data are averaged over time (96 seconds) and angle (nearly the full 4 pi), so narrow angular and/or temporal features are not shown. Higher temporal and angular resolution data can be interactively generated at http://lasp.colorado.edu/timas/mrdf
