Random groups HDUs. Note that the internal storage of random groups is a Object[ngroup][2] array. The first element of each group is the parameter data from that group. The second element is the data. The parameters should be a one dimensional array of the primitive types byte, short, int, long, float or double. The second element is a n-dimensional array of the same type. When analyzing group data structure only the first group is examined, but for a valid FITS file all groups must have the same structure.
The following tables list the members exposed by RandomGroupsHDU.
