Description
radialvelocity defines a radialvelocity measure from the CLI. It has to
specify a reference code, radialvelocity quantity value (see introduction for
the action on a
scalar quantity with either a vector or scalar value, and when a vector of
quantities is given), and optionally it
can specify an offset, which in itself has to be a radialvelocity.
Allowable reference codes are:
LSRK LSRD BARY GEO TOPO GALACTO.
Note that additional ones may become available. Check in Glish with:
- dm.listcodes(dm.radialvelocity())
[normal=LSRK LSRD BARY GEO TOPO GALACTO, extra=]
The radialvelocity quantity values should be given as velocity.
