PONGO has been updated to fix several problems with the BEGPLOT command. This now correctly selects the last AGI DATA picture when OVERLAY is set (so that for instance KAPPA images can be labelled), and avoids problems when selecting pictures using labels (which resulted in a runaway device open error condition).
If ICL is exited before closing PONGO (using the ENDPLOT command) a warning is now issued and an attempt to repair the AGI database is now made.
A bug in the ANNOTATE command has been fixed. This command now correctly handles the RACENTRE and DECCENTRE parameters.
All PONGO command descriptions now include a usage section. This shows the order of any positional parameters explicitly.
A new example procedure has been added to show the use of the VECT and PVECT commands and how to label astrometric projections. The AGI example has been expanded to show the results.
The routines PLOTFUN and FITCURVE have been changed to remove the NAG dependency of PONGO.
The FITCURVE command now fits a general, rather than a Chebyshev
polynomial and now has the ability to fit B-splines. Both these
functions can be re-plotted by the PLOTFUN command.
