PROCEDURE aacgmloadcoef :PURPOSE: A wrapper procedure to choose AACGM DLM or IDL-native routines to load the coefficients of AACGM conversion. Actually this procedure does load the coefficients for given year if AACGM DLM is available. 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: year: 4-digit year for which the AACGM coefficients are loaded. :Examples: aacgmloadcoef, 2005 :AUTHOR: Tomo Hori (E-mail: horit@stelab.nagoya-u.ac.jp) :HISTORY: 2011/10/04: created and got through the initial bug fixes $LastChangedBy: crussell $ $LastChangedDate: 2013-03-21 10:10:35 -0700 (Thu, 21 Mar 2013) $ $LastChangedRevision: 11857 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/erg/ground/radar/superdarn/sdaacgmlib/aacgmloadcoef.pro $
