Data Maintenance
All data reduction should be done with the FCRAO package of CLASS.
It's OK to work in all caps. Follow the basic procedure outlined
below.
For data acquisition while observing, or shortly afterward, first
enter the software package from the proper directory on fcrao and load
the default settings:
umigs% cd galaxydirectoryname (i.e., i342 or n253)
umigs% fcrao
FCRAO> @m:def
Load data from the modcomp (telescope computer) to a file:
FCRAO> @m:scanload
FCRAO> list
FCRAO> get first
FCRAO> plot
FCRAO> get next, get scannumber, whatever...
To add recent data on the same night to a previous file, omit
the "new" in file out, or say file both, and simply input the new scan
numbers.
To encorporate new data with a previous set (different date, concated or not):
FCRAO> @m:concatnew (fill in the requested info as prompted)
To coadd (average together) data:
FCRAO> @m:redux12co, and fill in the requested info from the
observations:
| NX: | NX from observations, source table |
| INFILE: | input file |
| OUTFILE: | output file (MUST BE DIFFERENT
FROM INPUT FILE!!) |
To examine the mean noise with position in a galaxy:
FCRAO> @m:plotrms, or
FCRAO> @m:plotrms0 if PA-90=-90
To examine the integrated intensity with position in a galaxy:
FCRAO> @m:ploti, or
FCRAO> @m:ploti0 if PA-90=-90
To examine the CO/13CO ratio with position in a galaxy:
FCRAO> @m:ratio, or
FCRAO> @m:ratio0 if PA-90=-90
