Does any one have a list of 12th mag radial velocity standards for DIS? Experience with using them? I need these for our program on velocities of halo stars ( to be sure that the backgrond targets we choose do not have strong stellar lines on top of the interstellar lines). The precision we need is not great, but I need to make a few checks to be sure all the signs are right and to ascertain how to budget our errors on fainter objects. Thanks. -- Dr. Donald G.
