We have obtained spectra in the H-β region for a sample of 244 of the 245 known δ Scuti variable stars north of -10° declination and brighter than 13th magnitude. We have also obtained a sample of rotational velocity standards in the same spectral region. From this we are assembling a catalog of rotational velocities for delta Scuti variables. We are studying and comparing two previously published methods for determining these rotational velocities. We will use one or both of these methods to calculate rotational velocities for the stars in our sample. In addition, we will determine the H-β color index for the stars in our data set. We will present a range of results.
