Upstream version 4.16

This package contains the source code for the fitsverify FITS file
conformance verification program. It is maintained by the HEASARC
at NASA/GSFC ( This is a stand-alone
version of the fverify task in the FTOOLS package.
The CFITSIO library, also available from the HEASARC, is required
to compile and build fitsverify. In particular, the fitsio.h, and
longnam.h include files are needed to compile the program, which
must then be linked with the CFITSIO library itself (i.e., the file
libcfitsio.a on unix systems).
fitsverify can be built on most unix machines with a command similar
to the following:
gcc -o fitsverify ftverify.c fvrf_data.c fvrf_file.c fvrf_head.c fvrf_key.c
fvrf_misc.c -DSTANDALONE -L. -lcfitsio -lm -lnsl -lsocket
(The '-lm', '-lnsl' and '-lsocket' library directives may not be
required on all platforms.)
Optionally, one may add the -DERR2OUT flag to force all the error
messages to go to stdout rather than stderr (usually only useful
if the output of fitsverify is being piped to another file or task).
To build fitsverify with Visual C++ on Windows PCs, first execute the
vcvars32.bat file that is distributed with vcc, unpack the fitverify
.zip file, then excute the following command:
cl /MD ftverify.c fvrf_data.c fvrf_file.c fvrf_head.c fvrf_key.c
fvrf_misc.c -DSTANDALONE cfitsio.lib
A help file describing the features of fitsverify can be produced
by entering the command 'fitsverify -h'. The help file
is reproduced below:
fitsverify -- Verify that the input files conform to the FITS Standard.
USAGE: fitsverify filename ... - verify one or more FITS files
(may use wildcard characters)
or fitsverify @filelist.txt - verify a list of FITS files
Optional flags:
-l list all header keywords
-q quiet; print one-line pass/fail summary per file
-e only test for error conditions (ignore warnings)
fitsverify exits with a status equal to the number of errors + warnings.
fitsverify -l m101.fits - produce a detailed verificaton report of
a single file, including a keyword listing
fitsverify -q *.fits *.fit - verify all files with .fits or .fit
extensions, writing a 1-line pass/fail
message for each file
This task reads one or more input FITS files and verifies that the
files conform to the specifications of the FITS Standard document
(known as the NASA/Science Office of Standards and Technology 'Definition
of the Current FITS Standard', document number, NOST 100-2.0, available
online at The input filename template may
contain wildcard characters, in which case all matching files will be
tested. Alternatively, the name of an ASCII text file containing a list
of file names, one per line, may be entered preceded by an '@' character.
The following error or warning conditions will be reported:
- Mandatory keyword not present or out of order
- Mandatory keyword has wrong datatype or illegal value
- END header keyword is not present
- Sum of table column widths is inconsistent with NAXIS1 value
- BLANK keyword present in image with floating-point datatype
- TNULLn keyword present for floating-point binary table column
- Bit column has non-zero fill bits or is not left adjusted
- ASCII TABLE column contains illegal value inconsistent with TFORMn
- Address to a variable length array not within the data heap
- Extraneous bytes in the FITS file following the last HDU
- Mandatory keyword values not expressed in fixed format
- Mandatory keyword duplicated elsewhere in the header
- Header contains illegal ASCII character (not ASCII 32 - 126)
- Keyword name contains illegal character
- Keyword value field has illegal format
- Value and comment fields not separated by a slash character
- END keyword not filled with blanks in columns 9 - 80
- Reserved keyword with wrong datatype or illegal value
- EXTEND not present in the primary array if there are extensions
- BLOCKED, if present, not among the first 36 keywords
- XTENSION keyword in the primary array
- Column related keyword (TFIELDS, TTYPEn,TFORMn, etc.) in an image
- SIMPLE, EXTEND, or BLOCKED keyword in any extension
- Image WCS keywords (CTYPEn, CRPIXn, CRVALn, etc.) in a table
- Table WCS keywords (TCTYPn, TCRPXn, TCRVLn, etc.) in an image
- TDIMn or THEAP keyword in an ASCII table
- TBCOLn keyword in a Binary table
- THEAP keyword in a binary table that has PCOUNT = 0
- XTENSION, TFORMn, TDISPn or TDIMn value contains leading space(s)
- Index of any WCS keyword (CRPIXn, CRVALn, etc.) greater than
value of WCSAXES
- Index of any table column descriptor keyword (TTYPEn, TFORMn,
etc.) greater than value of TFIELDS
- TSCALn or TZEROn present for an ASCII, logical, or Bit column
- TDISPn value is inconsistent with the column datatype
- Length of a variable length array greater than the maximum
length as given by the TFORMn keyword
- Logical column contains illegal value not equal to 'T', 'F', or 0
- Character string column contains non-ASCII text character
- Header fill bytes not all blanks
- Data fill bytes not all blanks in ASCII tables or all zeros
in any other type of HDU
- Gaps between defined ASCII table columns contain characters with
ASCII value > 127
- Presence of deprecated keywords BLOCKED or EPOCH
- 2 HDUs have identical EXTNAME, EXTVER, and EXTLEVEL values
- BSCALE or TSCALn value = 0.
- BLANK OR TNULLn value exceeds the legal range
- TFORMn has 'rAw' format and r is not a multiple of w
- DATE = 'dd/mm/yy' and yy is less than 10 (Y2K problem??)
- Index of any WCS keyword (CRPIXn, CRVALn, etc.) greater than
value of NAXIS, if the WCSAXES keyword is not present
- Duplicated keyword (except COMMENT, HISTORY, blank, etc.)
- Column name (TTYPEn) does not exist or contains characters
other than letter, digit and underscore
- Calculated checksum inconsistent with CHECKSUM or DATASUM keyword
