STEREO-B SECCHI HI Level 2 produced by UK Solar System Data Centre

ResourceID
spase://NASA/NumericalData/STEREO-B/SECCHI/HI/L2_RAL

Description

SECCHI HI Level 2 FITS files produced by the UK Solar System Data Centre, calibrated and background subtracted. Images stored in FITS files with filenames such as "20140101_180501_24h1A_br11.fts". The meaning of the different parts of this filename is as follows:

  • 20140101 is the observation date, 2014-01-01;
  • 180501 is the observation time, 18:05:01 UT;
  • 2 represents Level-2;
  • 4 is a code for the data units, where 4=Dn/Sec/Pixel, b=Mean Solar Brightness (MSB), and t=S10. MSB & S10 have the diffuse source correction applied;
  • h1 or h2 for HI-1 or HI-2;
  • A or B for STEREO-A or STEREO-B;
  • br for Buffinton/RAL background subtracted--a full running window where the F-corona is computed as the mean of the lowest quartile of pixels;
  • 11 is the length of the running window in days, usually either 01 or 11 for HI-1, and 03 or 11 for HI-2.
