mirage
Mirage was a nice standalone tool for analysis of multidimensional data, from which TOPCAT took some inspiration. It was described in a 2007 paper 2007ASPC..371..391H, but no significant development seems to have taken place since then. This format is therefore probably obsolete, but you can still write table output in Mirage-compatible format if you like.
If no output format is explicitly chosen,
writing to a filename with
the extension ".mirage" (case insensitive)
will select mirage format for output.
An example looks like this:
# # Written by uk.ac.starlink.mirage.MirageFormatter # Omitted column 5: MAMMAL(Boolean) # # Column names format var RECNO SPECIES NAME LEGS HEIGHT # # Text columns format text SPECIES format text NAME # # Table data 1 pig Pigling_Bland 4 0.8 2 cow Daisy 4 2.0 3 goldfish Dobbin <blank> 0.05 4 ant <blank> 6 0.001 5 ant <blank> 6 0.001 6 queen_ant Ma'am 6 0.002 7 human Mark 2 1.8
