The two AIPS++ tables, t1 and t7, used in the examples in this document were created from some GBT system test data from the 140-ft telescope. Other instruments, such as the VLA, will have a different file and directory structure for the original data from the one outlined below, but many properties of the created AIPS++ tables will be the same.
The original data are in several FITS Binary Table files written by different system modules, e.g., the weather monitor, telescope position control, and one of the data backends. The t1 table contains data from the continuum backend, and t7 is a bit of spectral processor data in spectral line mode. There will be an automated process to convert the raw FITS data into tables readable by AIPS++. For now, the data must be filled by hand. The utility to fill data from the GBT backends, for example, is called gbtmsfiller.
A step to opening tables within glish was hidden by the glishtutorial.g script. Namely, to open a table use:
- t7 := table('t7')
where the argument to the table() function is the directory produced by the
filler.
