As part of research astronomers gather and analyze information about stars' fundamental properties. One such piece of information lies in the hydrogen beta index, gathered through spectral observations. The H-β index is commonly used to measure surface temperature of stars as well as the age of stars or clusters. As such, it is a valuable piece of information for astronomical objects. In this study we present several hundred previously unpublished or updated H- β index values of δ Scuti variable stars. The values were calculated from a calibration using spectroscopic observations obtained at the Dominion Astrophysical Observatory of 190 δ Scuti stars north of --1 declination and brighter than 13th magnitude.
