public class FitsStarTable
extends uk.ac.starlink.table.RandomStarTable
An implementation of the StarTable interface which uses FITS TABLE
or BINTABLE extensions.
This implementation uses the table handling in the nom.tam.fits package. I think that performance could be considerably improved by rewriting the table access from scratch. The reason for this is largely that the nom.tam.fits classes do a lot of wrapping of values in (perhaps multi-dimensional) arrays, which is not for our purposes necessary. Such a re-implementation would take a bit of effort unfortunately.
This class should only be used for TABLE extension (that is ASCII table)
HDUs.
The BintableStarTable
class is much more efficient for BINTTABLE
extensions (binary table) HDUs.
