#### 4.1.2.13 Tab-Separated Table

Tab-Separated Table, or TST, is a text-based table format used by a number of astronomical tools including Starlink's GAIA and ESO's SkyCat on which it is based. A definition of the format can be found in Starlink Software Note 75.

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

An example looks like this:

    animals.vot

    # Table parameters
    Description: Some animals
    Author: Mark Taylor

    # Attempted guesses about identity of columns in the table.
    # These have been inferred from column UCDs and/or names
    # in the original table data.
    # The algorithm which identifies these columns is not particularly reliable,
    # so it is possible that these are incorrect.
    id_col: 2
    ra_col: -1
    dec_col: -1

    # This TST file generated by STIL v4.2-debian
