Command Line Arguments

filename Name of FITS or IRAF image file. This must be present.
-a rotation angle Output WCS rotation angle in degrees. The defauklt is to use the same rotation angle as the input image.
-b RA Dec Output center right ascension and declination in degrees or sexigesimal in B1950 (FK4). Sexigesimal coordinates are hours:minutes:seconds degrees:minutes:seconds. The default is to use the input center, using the values of the RA, DEC, and EPOCH keywords if there are no standard WCS keywords in the image header.
-e long lat Output center in ecliptic longitude and latitude in degrees.
-f FITS filename Use WCS from the header of this file. Other command line arguments can be used to override specific parameters. (Added in WCSTools 3.4.2)
-g long lat Output center in galactic longitude and latitude in degrees.
-i number Bits per pixel in output image as FITS BITPIX values; i.e. -64 and -32 are 8-byte and 4-byte floating point numbers, and 8, 16, and 32 are 1-byte, 2-byte, and 4-byte integers.
-j RA Dec Output center right ascension and declination in degrees or sexigesimal in J2000 (FK5). Sexigesimal coordinates are hours:minutes:seconds degrees:minutes:seconds. The default is to use the input center, using the values of the RA, DEC, and EPOCH keywords if there are no standard WCS keywords in the image header.
-l number Log every number rows of input image
-n number Integer pixel value for output pixels not set from input image. The BLANK header keyword is set to this value. (Added in WCSTools 3.4.2)
-o [filename] Write output to the file filename. The default is to write a file called remap.fits.
-p plate scale Output plate scale in arcseconds per pixel. The default is to use the values of the SECPIX or SECPIX1 and SECPIX2 keywords in the image header). The default is to use the same plate scale as the input image WCS.
-v print more information about processing
-w projection code The WCS projection of the output image, such as TAN. This is the last 3/8ths of the output CTYPE1 and CTYPE2 keyword values. The default is to use the same projection type as the input image.
The first five characters of these keywords are set based on the coordinate system:
  • RA--- and DEC-- for -b (B1950) or -j (J2000),
  • GLON- and GLAT- for -g (galactic), and
  • ELON- and ELAT- for -e (ecliptic).
  • -x Xref Yref Pixel coordinates of the reference pixel used in the output WCS projection The default is to translate the input reference pixel into the output system.
    -y Xdim Ydim horizontal and vertical dimensions of the output image. The default is to use the same as the input image.
