InformationURL Name PAPCO Software URL http://www.papco.org 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.

Depending on instrument mode, fluxes for each major species are accumulated for 2, 4, 8, 16, or 32 spins on-board. This corresponds to 12, 24, 48, 96, or 192 second resolution. The spin accumulation indicator shows the number of spins accumulated for each major ion species for each data record. Note that data with both high and medium resolution are combined in these files. This means that the energy, angle, and time resolution of some data are less than the resolution provided in the data file. Early in the mission, The TIMAS high energy limit was 22 keV/e. It was changed to 33 keV/e on June 26, 1996. The Energy_Range_ID flag indicates which energy range the TIMAS instrument was in at the time of data acquisition. Even energy steps (0, 2, ...) are acquired on even spin numbers and odd energy steps (1,3, ...) are acquired on odd spin numbers. High resolution data are included from two spins. To resolve timing uncertainties the Even/Odd indicator is set to indicate which set of energy steps were acquired in the first 6 seconds of the two spin accumulation interval. The quality of TIMAS data depends on the total number of counts processed by the detector. Some summary quality information is provided in the Quality Flags. The Quality Flags are derived from the fast event counter and other data sources. The TIMAS sensor responds to penetrating radiation that is particularly intense in the radiation belt part of each orbit. The Fluxes returned have been corrected for the background counting rate. Correction of TIMAS fluxes for high count rates increases the uncertainty in the flux values reported. The quality flag is provided as a convenient flag to use to select data that has been acquired in the linear response range of the instrument. Depending on instrument mode, fluxes for each major species are averaged or not averaged over energy ranges on-board. The energy resolution indicator provides a summary of the energy resolution of the data in each record for each ion species. Depending on instrument mode, fluxes for each major species are averaged with one of three angular resolutions on-board. The pitch angle resolution indicator provides a summary of the angular resolution of the data in each record for each ion species. 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. After this date the TIMAS K1 data product should be used instead.

These data were assembled from various data products with different energy resolution. Data are given with full 28 energy step resolution EVEN IF ONLY 7 energy step resolution data are available. This flag documents the resolution of the data included in the average. Values are: 0 All single spin 14 energy step data. 1 Mostly 14 energy step data. Some 7 energy step.

The quality flag is provided as a convenient flag to use to select data that has been acquired in the linear response range of the instrument. A quality flag is in the range 0-99 with the following values/meanings 0 OK. 1 Some data missing. 2 More than 5% data missing 3 Not used 4 Not used 5 Warning flags set 6 Not used 99 No valid data. 0-1 indicate high quality data while 2 indicates adequate quality data.
