1-second Count Rates from SAMPEX/LICA

Goto the data

This data set consists of 1-second energetic particle count rates from the LICA instrument. The data set covers the time period 9 October 1997 to 30 June 2004). Coverage starts when the instrument DPU was reprogrammed to provide these 1-s rates.

The data are a subset of the 6-second LICA count rates (D3+D4, D1+D2, stop, start, low priority, & high priority) provided at 1-second resolution.
See the 6 LICA -second rates documentation for more details.

Units are counts/second.

Data are currently provided as daily ASCII text files. Each file contains 7 columns:

• Second_of_Day
• D4+D3 : D4+D3 detector singles counts. Ions and electrons > 600 keV.
• D2+D1 : D4+D3 detector singles counts. Ions and electrons > 600 keV.
• Stop : STOP MCP Singles counts. > 250 KeV for protons, > 25 keV for e-.
• Start : START MCP Singles counts. > 250 KeV for protons, > 25 keV for e-.
• Low_Pri : Counts of particle events identified as He by the onboard logic. 0.50-6.57 MeV/nuc.
• High_Pri : Counts of particle events identified as Z>5 by the onboard logic. 0.49-10.7 MeV/nuc.
