Supplementary Notes
The RA and dec in the above table are from Samus et al. (2009).
All of the other data are taken from Stetson & West (1994).
This cluster lies in the Galactic plane and is subject to considerable
differential reddening.
HST CM diagrams by Fulton et al. (1999) and by Lee et al. (2001)
show a predominantly blue HB and a blue straggler sequence.

Discovery of the variable stars in NGC 6287:
V1-3
Sawyer (1943) with x,y positions and ID chart
V4-9
These are "candidate" variables announced by Stetson & West
(1994 - Table 4) with x,y positions.
The numbers V4-9 were assigned by Clement et al. (2001)
The SW numbers are listed in the remarks column.
