#### 5.1.2.7 `ipac`

Writes output in the format used by CalTech's Infrared Processing and Analysis Center, and defined at http://irsa.ipac.caltech.edu/applications/DDGEN/Doc/ipac_tbl.html. Column name, type, units and null values are written, as well as table parameters.

The handler behaviour may be modified by specifying one or more comma-separated name=value configuration options in parentheses after the handler name, e.g. "`ipac(maxCell=1000,maxParam=100000)`". The following options are available:

`maxCell = <int>`
  Maximum width in characters of an output table cell. Cells longer than this will be truncated.
`maxParam = <int>`
  Maximum width in characters of an output table parameter. Parameters with values longer than this will be truncated.
`params = true|false`
  Whether to output table parameters as well as row data.

If no output format is explicitly chosen, writing to a filename with the extension "`.tbl`" or "`.ipac`" (case insensitive) will select `IPAC` format for output.

An example looks like this:

    \Table name = "animals.vot"
    \Description = "Some animals"
    \Author = "Mark Taylor"
    | RECNO | SPECIES   | NAME          | LEGS | HEIGHT | MAMMAL |
    | int   | char      | char          | int  | double | char   |
    |       |           |               |      | m      |        |
    | null  | null      | null          | null | null   | null   |
      1       pig         Pigling Bland   4      0.8      true
      2       cow         Daisy           4      2.0      true
      3       goldfish    Dobbin          null   0.05     false
      4       ant         null            6      0.001    false
      5       ant         null            6      0.001    false
      6       queen ant   Ma'am           6      0.002    false
      7       human       Mark            2      1.8      true
