get_field_multi - return magnetic field vector for multiple locations¶

subroutine get_field_multi(ntime, kext, options, sysaxes, year, doy, ut, xin1, xin2, xin3, maginput, bxgeo, bl)¶

Parameters:

ntime [integer4,in] :: number of locations
kext [integer4,in] :: external magnetic field model number
options (5) [integer4,in] :: control options for calculation
sysaxes [integer4,in] :: coordinate system index see sysaxes
year (ntime_max) [integer4,in] :: years for locations
doy (ntime_max) [integer4,in] :: day of year for locations
ut (ntime_max) [real8,in] :: universal time [s] for locations
xin1 (ntime_max) [real8,in] :: 1st coordinate according to sysaxes
xin2 (ntime_max) [real8,in] :: 2nd coordinate according to sysaxes
xin3 (ntime_max) [real8,in] :: 3rd coordinate according to sysaxes
maginput (25,ntime_max) [real8,in] :: magnetic field inputs
bxgeo (3,ntime_max) [real8] :: magenetic field vector in GEO coordinates [nT]
bl (ntime_max) [real8] :: magnetic field magnitude [nT]

Description¶

Returns the GEO vector of the magnetic field at the input locations for the set of internal/external magnetic field selected.
