! Comments included after generating the output file begin with: '!' ! All lines beginning with '!' are not outputed by the program 'helios_3d_table.f' ! ! The output files are generated with the program 'helios_3d_table.f'. ! 2 modes High data mode (HDM) and Normal data mode (NDM). The i1a ! data matrix in the HDM mode dimension is 7x7x32 (azimut*elevation*energy), ! while in NDM data matrix dimension is 5x5x9. ! ! Description of the filename: 'h?y??d???h??m??s??'_?dm.x ! ! In file names the spacecraft id and time is encoded, ! e.g.: h1y75d002h03m57s09_hdm.0: ! h1 : spacecraft id (1= Helios 1, 2 = Helios 2) ! h1y75 : year (1975) ! h1y75d002 : day of year (2 day) ! h1y75d002h03 : hour (3 o'clock) ! h1y75d002h03m57 : minutes (57 minutes) ! h1y75d002h03m57s09 : seconds (9 seconds) ! h1y75d002h03m57s09_hdm : indicate data mode (_hdm or _ndm) ! h1y75d002h03m57s09_hdm.0 : indicate mode (0 = no shift, 1 = shift) ! ! means that the file contains data of the Helios 1 spacecraft recorded ! in the year 1975 at the 2. day (e.g. 2. Jan.) at time 3:57:09 in the ! 'hdm' mode, with 'no shift'. ! The files are located in the directories Y??D???: ! Y75 : year 1975 ! D002 : day of year 2 ! The directory Y75D002 is uncompressed approximately 35 Mbyte large, and ! compressed 13 Mbyte large. In the directory are 1960 files out of 2160 ! possible files (every 40 s one spectrum is taken, thus in one day ! 86400/40 files can be generated). Thus a directory can contain approximately ! 40 Mbyte (uncompressed, or 15 Mbyte compressed). The directories can ! be larger or smaller depending how many hdm or ndm files are in them. ---------------------------------Begin of data file-------------------------- -1.2 Degree, Pizzo correction ! see Pizzo et al. 1983, ApJ, 271, 335-354 351.583329 3.20930305 ! replaces the one fluid parameter v, ! and azimuth correction for effective solar diameter: |v|, and azimuth !generated by !helios_3d_table.f 0 0 0 0 1 !mode,shift,perihelion_shift, minus, i1a_3_on !mode = 0 = NDM; 1 = HDM !shift = 0,1 shift of azimuth angle, about half of the ! azimuth interval !perihelion_shift = 0,1 Helios 2 only; shift of the azimuth by ! 7.03 degree during perihelion passage !minus = 0, -1 qualifier if in HDM a data frame was not ! correct (i1a(x,y,z) = -1), but HDM can be handled as NDM ! i1a_3_on = 0 instrument i1a on; = 1 instrument i3 on 0.94349426 266.294189 -2.27541447 1623 ! spacecraft parameter ! heliopsheric distance in [AU], !
