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:\\n\\n* 20140101 is the observation date, 2014-01-01;\\n* 180501 is the observation time, 18:05:01 UT;\\n* 2 represents Level-2;\\n* 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;\\n* h1 or h2 for HI-1 or HI-2;\\n* A or B for STEREO-A or STEREO-B;\\n* 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;\\n* 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.\\n", "identifier": "/SDE/SPASE_JSON/|6d4345819cc429076a251edf56f12800", "keyword": ["imageintensity"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "UK Solar System Data Centre;UKSSDC;STEREO Science Center;SSC"}, "theme": ["Heliophysics"], "title": "STEREO-A SECCHI HI Level 2 produced by UK Solar System Data Centre"}
