This index will be used automatically + by funtools filtering of that column, provided the index file's modification +date is later than that of the data file. +.PP +The first required argument is the name of the \s-1FITS\s0 binary table +to index. Please note that text files cannot be indexed at this time. +The second required argument is the column (key) name to index. While +multiple keys can be specified in principle, the funtools index processing +assume a single key and will not recognize files containing multiple keys. +.PP +By default, the output index file name is [root]_[key].idx, where [root] +is the root of the input file. Funtools looks for this specific file name +when deciding whether to use an index for faster filtering. Therefore, the +optional third argument (output file name) should not be used for funtools +processing. +.PP +For example, to create an index on column Y for a given \s-1FITS\s0 file, use: +.PP +.Vb 1 +\& funindex foo.fits Y +.Ve +.PP +This will generate an index named foo_y.idx, which will be used by funtools +for filters involving the Y column. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +See funtools(7) for a list of Funtools help pages |
