ZCB STEREO-B 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. spase://SMWG/Person/William.T.Thompson GeneralContact UKSSDC - STEREO HI data processing documentation https://www.ukssdc.ac.uk/solar/stereo/documentation/HI_processing_L2_data.html spase://VSPO/NumericalData/STEREO-B/SECCHI/HI/L2_RAL spase://SMWG/Repository/STFC/RAL/UKSSDC Online Open UKSSDC - STEREO Archive data access https://www.ukssdc.ac.uk/solar/stereo/data.html Text spase://SMWG/Repository/NASA/GSFC/STEREO_SC Online Open https://spdx.org/licenses/ SPDX CC0-1.0 https://spdx.org/licenses/CC0-1.0.html Creative Commons Zero v1.0 Universal CC0 1.0 Universal is the Creative Commons license applicable to all publicly available NASA Heliophysics data products STEREO Science Center https://stereo-ssc.nascom.nasa.gov/data/ins_data/secchi_hi/ Text spase://SMWG/Instrument/STEREO-B/SECCHI ImageIntensity 2006-10-01T00:00:00Z -P15D Heliosphere.Inner Heliosphere.Remote1AU Sun.Corona
