Reading REGO data
REGO raw images (stream0) are stored in PGM files, with 20 frames stacked in each file (corresponding to one minute of data per file).  The PGM files are formatted such that THEMIS-ASI software for reading the stream0 images will work on REGO data.   A copy of themis_imager_readfile and pam_readfile are in the IDL REGO/software/IDL/ directory.

When using these codes; compile pam_readfile_new first, then themis_imager_readfile_new.  An example usage of the code is below. 


       themis_imager_readfile_new,filename,img,meta,/all

       img will be an array of (512,512, N images in the file)
       meta will be a structure of N elements that contains the meta data for each frame
       
       
       IDL> help,img
IMG             UINT      = Array[512, 512, 20]
       
       IDL> help,meta,/str
