## ERG_LOAD_CAMERA_OMTI_ASI

[Next Routine] [List of Routines]

     PROCEDURE: erg_load_camera_omti_asi

     PURPOSE:
       To load the OMTI ASI data from the ISEE ERG-SC site

     KEYWORDS:
       site  = Observatory name, example, erg_load_camera_omti_asi, site='sgk'.
               The default is 'all', i.e., load all available stations.
               This can be an array of strings, e.g., ['sgk', 'sta']
               or a single string delimited by spaces, e.g., 'sgk sta'.
               Sites: abu ath drw eur gak hlk hus isg ist ith kap ktb mgd nai nyr ptk rik rsb sgk sta syo trs yng
       wavelength = Wavelength in Angstrom, i.e., 5577, 6300, 7200, 7774, 5893, etc.
                    The default is 5577. This can be an array of integers, e.g., [5577, 6300]
                    or strings, e.g., '5577', '5577 6300', and ['5577', '6300'].
       /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 = (Optional) Time range of interest  (2 element array).
       /timeclip, if set, then data are clipped to the time range set by timespan

     EXAMPLE:
       erg_load_camera_omti_asi, site='sgk', wavelength=5577, trange=['2012-01-01/00:00:00','2012-01-02/00:00:00']
