Abstract:
BV photometry is provided for 1,234 stars in the magnitude range 13-18
in an annulus between 5 and 20 arc seconds from the center of NGC 1851
and for 1,247 stars in the magnitude range 18-23 at a distance of more
than 240 arc seconds from the center. For stars in the magnitude range
16-21, the errors in B-V increase with magnitude from 0.005 mag. to
0.022 mag.
See the document file (walker.txt or walker.tex) by Nancy G. Roman for
