The list below is a modified version of a table of spectral types for
low-mass stars in the Scorpius OB association observed by Preibisch et al.
I have obtained improved coordinates from 2MASS, UCAC1, or GSC-2.2, and added
photo-blue magnitudes from GSC-2.2 or USNO-B1.0. The source positions have
errors of up to 2".5.
I matched the list in VizieR against IRAS point-/faint-/serendipitous-
source catalogues, MSX, and GCVS v4.1---no matches in any of these surveys(!).
The R magnitudes are those given by Preibisch et al. I have added 'e'
to the spectral types for all those stars showing H-alpha emission (data in
the same source table).
Although it is not certain, the objects USco 160508.3-201531 and
USco 160508.5-201532 seem to be identical: the relevant star is not double on
any of the scanned DSS images or in the 2MASS images; at ~3" separation it
should be readily detectable, even if not resolved in various catalogues.
