freqshift
NAME
freqshift - change the frequency value in scn
SYNOPSIS
freqshift -freq_shift freq_in_MHz
-rest_freq freq_in_GHz
DESCRIPTION
The command changes the rest frequency in the header of scn flow.
The command automatically adjusts the nomical center frequency of the backend.
Therefore, the frequency relation between at antenna and on backend is kept.
The command is useful, when you want to show the velocity
for the different rest frequency from observed tracking frequency.
FILTER TYPE
.scn | freqshift | .scn
OPTIONS
- -freq_shift freq_in_MHz
- Give a frequency shift in MHz.
- -rest_freq freq_in_GHz
- Give a new rest_freq in GHz.
DEFAULTS
- -freq_shift 0 -rest_freq 0 -prm freqshift.prm
ENVIRONMENT
SEE ALSO
headcorr, headlist, .scn
BUGS
- Two options -freq_shift and -rest_freq are not effective simultaneously.
The positive -rest_freq value resets -freq_shift to be 0.
