the strange coordinates you mention are in degrees, my friend!

VOSpec admits the following string coordinates formats for RA:

DD:MM:SS.SSS
18:36:56.336 is 18degrees, 36 minutes, 56.336 seconds (degrees are the
default)(transformed to 19.538933333 degrees by VOSpec)

DDh:MM:SS.SSS
18h:36:56.336 is 18hours, 36 minutes, 56.336 seconds,
(transformed to 271.538933333333 degrees by VOSpec)

DDd:MM:SS.SSS
18d:36:56.336 is 18degrees, 36 minutes, 56.336 seconds,
(transform to 19.538933333 degrees by VOSpec)

DDh:MMm:SS.SSSs
of course, you could also add "m" and "s" to any of the previous
formats, e.g., 18h:36m:56.336s
(transformed to 271.538933333333 degrees by VOSpec)

This is described in the VOSpec help pages
http://esavo.esac.esa.int/VOSpecManual/gui.html#target

(no complain) :)
