New DDO Photometric Equatorial Standard Stars Between 9.0 < M48 < 16.0: Preliminary Results

We have begun an undertaking of adding to the DDO standard star list by integrating the popular Landolt (1992) equatorial standard star fields. Our new primary DDO standard stars include the principal UBVR_CI_C stars in the equatorial SA fields with fainter stars becoming our secondary standards for that field. We present our preliminary results for the primary standard stars in SA fields 92 through 106 with magnitudes between 9.0 < M₄₈ < 16.0. Secondary standard stars with magnitudes between 16.0 < M₄₈ < 22.0 will be presented in a subsequent paper.
