nsfits2scn
NAME
nsfits2scn - read profile FITS created by NRO newstar and make scn flow
SYNOPSIS
nsfits2scn [ -scn scn_name ]
[ -fit FITS ] [ -rest_freq in_GHz ]
[ -v LSR_velocity ]
[ -fitsheader filename ]
[ -kill_scale | -use_scale ]
[ -hpbw no|freq|size_in_arcsec ]
[ -freq_unit yes|no ]
DESCRIPTION
NRO newstar can create profile data in randam group FITS format.
This command convert the FITS in this type into scn flow.
A FITS file will create a single flow.
The header information reflects as many detail as possible from
the FITS header.
FILTER TYPE
.scn | nsfits2scn | .scn
OPTIONS
- -scn scn_name
- The main part of the output scn name.
In the final scn name 6 digits are attached.
- -fit FITS_filename_in_UNIX
- The input FITS file name.
- -rest_freq in_GHz
- If you want to give the rest_freq by yourself, you can use this option.
- -v LSR_velocity_in_km/s
- If you want to give the v_lsr by yourself, you can use this option.
- -fitsheader filename
- Asign the full filename for FITS headers to check the original FITS header.
Character "-" as a filename means standard error output (stderr) of OS.
- -kill_scale | -use_scale
- Switch the SCFACT keyword as a scaling factor of the profile.
Option -kill_scale gives 1.0 as a scaling factor in scn files.
- -hpbw no|freq|size_in_arcsec ]
- Input beamsize even if FITS has no information on that.
- The parameter value "freq" means HPBW is automatically calculated using
observation frequency and telescope name.
- If you want to set the exact value, you should give it in arcsec.
- -freq_unit yes|no
- NSFITS has a keyword "FQTRK" for observation frequency.
Its value should be in Hz but in GHz actually.
The parameter value "yes" means adjust this bug automatically.
DEFAULTS
- -scn is the same as input FITS name.
- -v is automatically set from FITS header
- -rest_freq is automatically set from FITS header
- -prm nsfits2scn.prm
- -fitsheader fitshead.txt
- -kill_scale
- -hpbw freq
- -freq_unit yes

BUGS
- Not all FITS format can be supported.
This command is sensitive to the FITS header keyword structure.
