1. cband resonances
The cband receiver was searched for resonances in the omt by doing 1 minute on/off position switching on VirgoA. ... The omt of lbw,sbw is at 70 K while the cband omt is at 20K. The Off positions will not have a bump at the resonance since the omt 20K temperature is close to that of the scattered radiation coming in through the horn. ... It did not give very good band passes. ... the top plot blue line at -10 Mhz. ... The two blue lines are the polA band passes +/- 80 MHz from the resonance bandpass. ...

3. Passing arguments to the shell
Shell scripts can act like standard UNIX commands and take arguments from the command line. Arguments are passed from the command line into a shell program using the positional parameters $1 through to $9 . Each parameter corresponds to the position of the argument on the command line. ... For example: cat printps # This script converts ASCII files to PostScript # and sends them to the PostScript printer ps1 # It uses a local utility "a2ps" a2ps $* | lpr -Pps1 printps elm.txt vi.ref msg . ...
