auroral_zone.pro

FUNCTION: auroral_zone PURPOSE: IDL function to calculate auroral zone position as a function of magnetic local time (mlt: 0.0-24.0 hours), activity index Q (q: 0-6).

auroral_zone_ssc.pro

FUNCTION: auroral_zone_ssc PURPOSE: Given an array of MLT values, returns latitudes of the auroral zone boundaries.

datesec_doy.pro

FUNCTION: DATESEC_DOY DESCRIPTION: take args for year and day of year and return (double float) seconds since 1 Jan 1970, 00:00 UT.

datetimesec_doy.pro

FUNCTION: DATETIMESEC_DOY DESCRIPTION: function to return seconds since 1/1/1970 00:00 UT, from date and time given as day, month, year, hour, minute, second, millisecond.

dipole_offset.pro

FUNCTION: dipole_offset PURPOSE: Calculate the location of the dipole using the IGRF coefficients and their secular variation.

label_foot_ticks.pro

PROCEDURE: label_foot_ticks PURPOSE: Keeps track of parasites on the pedal area of the body.

mag_to_geo.pro

PROCEDURE: mag_to_geoPURPOSE: Converts lattitude and longitude between MAG and GEO coordinates.
