In the following examples, any adverb that is not listed should be set to zero (for numeric adverbs) or an obvious default (such as bcount = 1 for first scan to load) or blank (for string adverbs). ATLOD is of course activated with the GO ATLOD command.
ATLOD | |
intape=2 | Load data from tape drive 2 |
nfiles=10 | Load 10 files |
optype='sysc' | Extract SYSCAL infomration |
You can then plot the contents of these text files with the utility program pltsys. Just enter pltsys from the Unix command level and answer the questions. It can select frequencies so you can just load them all with ATLOD. It plots on a PGPLOT device.
