votable

votable converts a VOTable to a FITS table, CSV, text or an SVG finding chart.

The input is a VOTable from cone -o file.xml (see cone) or from any VO tool; it must be a VOTable, not FITS. votable works offline.

Usage

munipack votable [options] -o output file.xml

Options

Option	Default	Description
-o, --output file	votable.fits	Output file; always give it.
--type fits|csv|txt|svg|xml	by suffix	Output format.
--verbose	off	Verbose messages.
-h, --help	—	Show the help.

SVG chart

Option	Default	Description
-pt projection	TAN	Projection (only gnomonic is implemented).
-pa deg	—	RA of the chart centre.
-pd deg	—	Dec of the chart centre.
-ps px/deg	—	Chart scale.
-pw px	500	Canvas width (use together with -ph).
-ph px	500	Canvas height (use together with -pw).
-ml mag	—	Reference magnitude for symbol size; fainter stars are drawn smaller.
--col-ra field	—	RA field, e.g. RAJ2000.
--col-dec field	—	Dec field, e.g. DEJ2000.
--col-mag field	—	Magnitude field, e.g. f.mag.

Output

One file in the format chosen by --type or by the suffix of -o: a FITS table, CSV, tab-separated text, an SVG chart, or a VOTable again.

Examples

Convert a cone search to a FITS table or a CSV file:

munipack votable -o pleiades.fits pleiades.xml
munipack votable -o pleiades.csv pleiades.xml

An 800 × 600 px finding chart of M67:

munipack cone -r 0.1 -o m67.xml -- 132.85 11.81
munipack votable -o m67.svg -pa 132.85 -pd 11.81 -ps 4000 -ml 16 -pw 800 -ph 600 \
    --col-ra RAJ2000 --col-dec DEJ2000 --col-mag f.mag m67.xml

Notes

• For a chart, always give -pa, -pd, -ps, -ml and the three --col-* names: they have no usable defaults, and the field names must match the VOTable exactly.

• North is up and east is left on the chart.
