nom.tam.fits.RandomGroupsData
- All Implemented Interfaces:
FitsElement
This class instantiates FITS Random Groups data. Random groups are
instantiated as a two-dimensional array of objects. The first dimension of
the array is the number of groups. The second dimension is 2. The first
object in every row is a one dimensional parameter array. The second element
is the n-dimensional data array.
