NAME: 3d_structure PURPOSE: Documentation for the 3d structure. This is NOT a procedure or a function. It is ONLY Documentation. don't try to run it! The 3d structure is the standard structure that contains all information necessary to do data analysis on a particle distribution function. The following is an example structure obtained from the WIND data set: ** Structure <1b689b0>, 29 tags, length=35304, refs=1: PROJECT_NAME STRING 'Wind 3D Plasma' DATA_NAME STRING 'Eesa Low' UNITS_NAME STRING 'Counts' Current Units. TIME DOUBLE 8.2313292e+08 Sample start. Secs since 1970 END_TIME DOUBLE 8.2313292e+08 Sample End. Secs since 1970. INTEG_T DOUBLE 3.0000000 Integration Time. Seconds. NBINS INT 88 number of angle bins. NENERGY INT 15 number of energy bins. MAP INT Array(32, 32) bin map (req'd only for plot3d_new) DATA FLOAT Array(15, 88) ENERGY FLOAT Array(15, 88) THETA FLOAT Array(15, 88) PHI FLOAT Array(15, 88) GEOM FLOAT Array(15, 88) Req'd by convert_esa_units DENERGY FLOAT Array(15, 88) DTHETA FLOAT Array(15, 88) DPHI FLOAT Array(15, 88) DOMEGA FLOAT Array(15, 88) EFF FLOAT Array(15, 88) Req'd by convert_esa_units FEFF FLOAT Array(15, 88) Req'd by convert_esa_units MASS DOUBLE 5.6856593e-06 GEOMFACTOR DOUBLE 0.00039375000 Req'd by convert_esa_units VALID LONG 1 SPIN LONG 17152 (Optional) UNITS_PROCEDURE STRING 'convert_esa_units' MAGF FLOAT Array(3) (Optional magnetic field vec.) VSW FLOAT Array(3) (Optional flow velocity vec.) The following functions will return a 3d structure: For the WIND data set: ("LOAD_3DP_DATA" must be called first.) "GET_EL", "GET_PL","GET_EH","GET_PH","GET_PLB","GET_PHB","GET_ELB", "GET_EHS","GET_SF","GET_SO","GET_SFB","GET_SOB" For the GIOTTO data set: "GET_GI" For the CLUSTER data set: In Progress.... For the FAST data set: In Progress.... Once the 3d structure is obtained then it can be displayed with the following routines: "SPEC3D", "PLOT3D", "CONT3D" The following routines are useful for manipulating the data: "CONV_UNITS", "CONVERT_VFRAME", "PAD"
