fitstopnm - convert a FITS file into a portable anymap SYNOPSIS
fitstopnm [-image N] [-noraw] [-scanmax] [-printmax] [-min f] [-max f] [FITSfile] DESCRIPTION
Reads a FITS file as input. Produces a portable pixmap if the FITS file consists of 3 image planes (NAXIS = 3 and NAXIS3 = 3), a portable graymap if the FITS file consists of 2 image planes (NAXIS = 2), or whenever the -image flag is specified. The results may need to be flipped top for bottom; if so, just pipe the output through pnmflip -tb. OPTIONS
The -image option is for FITS files with three axes. The assumption is that the third axis is for multiple images, and this option lets you select which one you want. Flags -min and -max can be used to override the min and max values as read from the FITS header or the image data if no DATAMIN and DATAMAX keywords are found. Flag -scanmax can be used to force the program to scan the data even when DATAMIN and DATAMAX are found in the header. If -printmax is specified, the program will just print the min and max values and quit. Flag -noraw can be used to force the program to produce an ASCII portable anymap. The program will tell what kind of anymap is writing. All flags can be abbreviated to their shortest unique prefix. REFERENCES
FITS stands for Flexible Image Transport System. A full description can be found in Astronomy & Astrophysics Supplement Series 44 (1981), page 363. SEE ALSO

fitsort - sort FITS header information from a list of files SYNOPSIS
dfits <FITS files...> | fitsort <FITS keywords...> DESCRIPTION
fitsort extract keyword values from a set of FITS headers and outputs it in an ASCII table format, which is compatible with most data pro- cessing software packages. It shall only be used in combination with the dfits utility. The ASCII output is shown in columns. Columns are aligned with blank characters and also separated by tabulations. Blank alignment allows human readers to visualize the output in a pretty format, tabulations are there for spreadsheet compatibility. If you want to load out fit- sort output into any spreadsheet, specify that fields shall be separated by tabulations and entries separated by linefeeds. Examples : dfits *.fits | fitsort BITPIX NAXIS NAXIS1 NAXIS2 The output would look like: FILE BITPIX NAXIS NAXIS1 NAXIS2 file0001.fits 16 2 128 128 file0002.fits 32 2 512 512 ... ESO specific features in the FITS header are also supported. To get values for 'HIERARCH ESO' keywords, just give the complete names within double quotes. e.g. dfits *.fits | fitsort "HIERARCH ESO INS LENS" Another way of giving HIERARCH ESO keywords is to use the short FITS notation, the above example can be given as: dfits *.fits | fitsort INS.LENS Example: to retrieve the DPR keywords from an ESO FITS header, you would use: dfits *.fits | fitsort To be completed... DPR.CATG DPR.TYPE DPR.TECH This second way of requesting HIERARCH ESO keywords is not only shorter to type, it also avoids typing quotes or double-quotes on the com- mand-line, making it easier to script with fitsort. Notice that the keywords you give on the command-line are case-insensitive. The above line is equivalent to: dfits *.fits | fitsort dpr.catg dpr.type dpr.tech OPTIONS
-d Do not print out the first output line. This option is useful to get only the query results, without the top line (giving all column names). This makes it easy to script fitsort from programs like awk or perl. FILES
Input files to dfits shall all comply with FITS format. fitsort also supports HIERARCH ESO FITS format. SEE ALSO
