PROCEDURE aacgmconvcoord :PURPOSE: A wrapper procedure to choose AACGM DLM or IDL-native routines to convert (lat,lon) between Geographic coordinates and AACGM. The wrapper procedures/functions check !sdarn.aacgm_dlm_exists (if not defined, then define it by sd_init) to select appropriate AACGM routines (DLM, or IDL native ones attached to TDAS). :Params: glat, glon: Geographic latitude and longitude. mlat, mlon: AACGM latitude and longitude. alt: Altitude for conversion. err: Error status of coordinate transformation. :Keywords: TO_AACGM: Set to convert from geographic to AACGM coordinates. TO_GEO: Set to convert from AACGM to geographic coordinates. :Examples: aacgmconvcoord, glat,glon,alt, mlat,mlon,err, /TO_AACGM aacgmconvcoord, mlat,mlon,alt, glat,glon,err, /TO_GEO :AUTHOR: Tomo Hori (E-mail: horit@stelab.nagoya-u.ac.jp) :HISTORY: 2011/10/04: created and got through the initial bug fixes $LastChangedBy: lphilpott $ $LastChangedDate: 2011-10-14 09:20:31 -0700 (Fri, 14 Oct 2011) $ $LastChangedRevision: 9113 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/erg/ground/radar/superdarn/sdaacgmlib/aacgmconvcoord.pro $
