Routine Descriptions

ERG_LOAD_ISEE_VLF

 PROCEDURE: ERG_LOAD_ISEE_VLF

 PURPOSE:
   To load VLF spectrum data obtained by ISEE ELF/VLF network from the ISEE ERG-SC site

 KEYWORDS:
   site  = Observatory name, example, erg_load_isee_vlf, site='ath',
           the default is 'all', i.e., load all available stations.
           This can be an array of strings, e.g., ['ath', 'kap']
           or a single string delimited by spaces, e.g., 'ath kap'.
           Available sites as of July, 2017 : ath, kap, gak, ist, mam
   downloadonly : if set, then only download the data, do not load it into variables.
   no_server : use only files which are online locally.
   no_download : use only files which are online locally. (Identical to no_server keyword.)
   trange : Time range of interest  (2 element array).
   timeclip :  if set, then data are time clipped.

   cal_gain : if set, frequency-dependent gain of the antenna system is calibrated.
              The unit of gain G(f) is V/T, and calibrated spectral power P(f)
              at frequecy f is computed as

               P(f) = S(f)/ (G(f)^2) [nT^2/Hz],

              where S(f) is uncaibrated spectral power in unit of V^2/Hz.

 EXAMPLE:
   erg_load_isee_vlf, site='ath', $
         trange=['2015-03-17/00:00:00','2015-03-17/02:00:00']
