use_all_info_params

For speed, only a few summary info parameters are read from an image FITS file. These summary info parameters are in a separate single extension in the FITS file and include times, energy bands, and a few other items for every image. The rest of the info parameters for each image are in separate extensions, one for each image. If USE_ALL_INFO_PARAMS is set, then all of these separate extensions are read, and the info parameters in the object are filled in for each image. This can take a while for large image cube files.
