rawtran - RAW to FITS converter
rawtran [options] file(s)
Rawtran is an utility to convert of raw photos in .CR2, .CRW, MRW, NEF, RAF, etc. formats to the general astronomical FITS image format . The identification of raw photo type and decoding itself is done via DCRAW utility by D.Coffin . Dcraw should be available independently. This manual page summarises usage only. Visit homepage  for additional description.
-c [X|Y|Z|R|V|B|clear|scotopic], [Ri,Gi,Gi1,Gi2,Bi] or [plain,all] Select a colour band. -o filename Specify an output file name. If this option is not used, the output filename is determined from the input: any suffix like *.CR2 is replaced by *.fits. Precede the filename with exclamation point(!) to overwrite an existing file. --no-clobber do not overwrite an existing file -eV Values are stored as an energy-like rather than photon-like quantity. -D RAW dark filename Use the raw photo as a dark frame. Rawtran will try to convert the file to PGM format by the dcraw recommended command `dcraw -D -4 -j -t 0 file.RAW' and pass it as `dcraw -K file.pgm'. Note that sometimes can be necessary to switch-off automatic frame rotation by using -A "-t 0" option. -E FITS dark filename Use the FITS file as a dark frame. The FITS file must be previously converted as `dcraw -D -4 -j -t 0 dark.RAW'. -C options Conversions options for dcraw. Default is '-4 -o 5' for standard photometry filters and '-4 -D' for instrumental bands. Defaults are usually satisfactory -X options Specify options to conversion by dcraw itself. One represents default parameters: '-q 3 -w'. See also -A. -A options Specify additional options to dcraw itself. If you passed an option with parameter or more options, please, enclose ones to quotes or apostrophes. In doubts, use -X "-v" to show detailed description of conversion by dcraw. -h, --help Show summary of options. --version Display software version.
0 indicates successful run. A non-zero value is returned when an error occurred during conversion: 1 means and general error, 2 any RAW file(s) conversion has failed. If the utility is launched without options or with -h switch, zero means that rawtran's internal checker can run dcraw binary and non-zero value otherwise.
Produce a colour FITS and show it in xmunipack: $ rawtran -o IMG_0666.fits IMG_0666.CR2 $ xmunipack IMG_0666.fits A large set of RAW images can be converted as: $ rawtran *.CR2 Convert an image to be equivalent to humans eye brightness sensitivity at day: $ rawtran -c Y -o IMG_0666_Y.fits IMG_0666.CR2 Convert an image to be nearly equivalent to Landolt's B filter: $ rawtran -c B -o IMG_0666_B.fits IMG_0666.CR2 Get green component of RAW: $ rawtran -c Gi -o IMG_0666_Gi.fits IMG_0666.CR2 Subtract dark frame: $ rawtran -D IMG_DARK.CR2 IMG_0666.CR2
