1. Create Simple Header
The command
$ newfits null.fits
creates a dataless file having the follow header:
SIMPLE = T
BITPIX = 0
NAXIS = 2
NAXIS1 = 100
NAXIS2 = 100
COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy
COMMENT and Astrophysics' vol 376, page 359; bibcode 2001A&A...376..359H.
END
2. Create Header with WCS
The command
$ newfits -j 10:00 10:00 -p 0.5 -s 1024 1024 null.fits
creates a dataless file having the follow header:
SIMPLE = T
BITPIX = 0
NAXIS = 2
NAXIS1 = 1024
NAXIS2 = 1024
CRVAL1 = 150.00000000
CRVAL2 = 10.00000000
RA = '10:00:00.000'
DEC = '+10:00:00.00'
EPOCH = 2000
EQUINOX = 2000
RADECSYS= 'FK5 '
CRPIX1 = 512.500
CRPIX2 = 512.500
SECPIX = 0.50000
CDELT1 = -0.00013889
CDELT2 = 0.00013889
CTYPE1 = 'RA---TAN'
CTYPE2 = 'DEC--TAN'
CD1_1 = -0.000138890
CD1_2 = 0.000000000
CD2_1 = 0.000000000
CD2_2 = 0.000138890
COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy
COMMENT and Astrophysics' vol 376, page 359; bibcode 2001A&A...376..359H.
END
3. Create Simple Blank Image File
The command
$ newfits -o 16 null.fits
creates the FITS file null.fits
full of zeroes with the following header:
SIMPLE = T
BITPIX = 16
NAXIS = 2
NAXIS1 = 100
NAXIS2 = 100
COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy
COMMENT and Astrophysics' vol 376, page 359; bibcode 2001A&A...376..359H.
END
3. Create FITS File with Data
The command
$ newfits -o 16 -s 100 100 -i test.data+4 test.fits
creates the FITS file test.fits
filled with the contents of the file test.data except for the first:
SIMPLE = T
BITPIX = 16
NAXIS = 2
NAXIS1 = 100
NAXIS2 = 100
HISTORY Pixels from file test.data
COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy
COMMENT and Astrophysics' vol 376, page 359; bibcode 2001A&A...376..359H.
