FitsStarTable (Starjava FITS API)

java.lang.Object
- uk.ac.starlink.table.AbstractStarTable
- - uk.ac.starlink.table.RandomStarTable
  - - uk.ac.starlink.fits.FitsStarTable

All Implemented Interfaces:

uk.ac.starlink.table.StarTable
```
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.
