SIT Level 1 and Level 2 Data Description

The SIT Level 1 and Level 2 data are energetic particle intensities (1/(cm^2 s sr MeV/nuc)) for 4 species (H, 4He, O, and Fe), in ~10 energy-bins per species.

The highest time-resolution data provided by SIT is 1 minute. On this website, we provide the 1-minute data (Level 1 data) in ASCII text files, with each file containing one day of data, for one species, for one spacecraft (ahead or behind).

We also provide "Level 2 data", as follows: 10-minute data in ASCII text files, with each file containing one month of data, and hourly-averaged and daily-averaged files with each file containing one calendar year of data.

Each ASCII file begins with a header that provides version and other provenance information, and describes each data field.

The SIT 1-minute data are also available in CDF format, from the STEREO IMPACT Data portal at Berkeley. The Berkeley CDF files are generated using on-board lookup tables; the files at the Caltech site use pulse-height data and therefore have a more accurate calibration but sometimes lower statistical accuracy.
