NAME: AACGMIDL PURPOSE: This library is a pure IDL version of the AACGM library ROUTINES: EQN_OF_TIME equation of time SOLAR_LOC find location of sun CNV_AACGM convert coordinates to/from magnetic/geographic CALC_MLT calculate magnetic local time LOAD_COEF load a set of AACGM coefficients
NAME: EQN_OF_TIME PURPOSE: equation of time for a given longitude and year Calling sequence: eqt = eqn_of_time(mean_lon,yr)
NAME: SOLAR_LOC PURPOSE: location of the sun for given year and time Calling sequence: solar_loc,yr,t1,mean_lon,dec t1 is the seconds from the start of year. the mean longitude and declination are returned in mean_lon and dec as floats.
NAME: CNV_AACGM PURPOSE: convert to and from AACGM and Geographic coordinates Calling sequence: CNV_AACGM,in_lat,in_lon,height,out_lat,out_lon,r,error the calculated latitude and longitude for the given height are returned in out_lat,out_lon.
NAME: CALC_MLT PURPOSE: calculate magnetic local time for a given longitude Calling sequence: mlt=CALC_MLT(yr,t0,mlong) t1 is the seconds from the start of year and mlong is the magnetic longitude of the observing point.
NAME: LOAD_COEF PURPOSE: load a set of AACGM coefficients Calling sequence: load_coef,fname fname is the filename.
