The context ASTROMET can be enabled by the command SET/CONTEXT
ASTROMET. While in the original implementation everything was done
in one programme, in the context ASTROMET the software is split into
three commands. These commands take care of the following:
- read the measurements and standard stars, and compute the
transformation parameters (this step is performed by the
command ASTROMET/TRANSFORM);
- edit the standard star table to remove/restore some stars (this
step is performed by the command ASTROMET/EDIT);
- actually compute the converted coordinates (this step is
performed by the command ASTROMET/COMPUTE).
Steps 1 and 2 can be iterated until a satisfactory result is obtained.
The whole process can also be executed in an iterative way by the
command ASTROMET/POS1. This commands asks for all input
parameters.
