The Sloan Digital Sky Survey (SDSS) has achieved first light. Though still in the engineering shakedown year, the image quality of some of these early runs is useable for science results.

Although similar to the Thuan-Gunn ugriz system, the SDSS u'g'r'i'z' system has wider effective bandwidths and covers almost the entire spectrum from the 3000~Å\/ to 11\,000~Å. This is a new photometric system; therefore, calibration of a network of primary standard stars is needed before the survey science results can be interpreted properly.

Beginning in earnest in March 1998, we started the calibration observations to define the SDSS u'g'r'i'z' standard star system using the 40-inch Ritchey-Chrétien telescope at the United States Naval Observatory's Flagstaff, Arizona Station. Future observations will also be made with a 20-in DFM telescope recently installed at Apache Point Observatory in New Mexico. In this paper, we will describe the software used to obtain and to reduce the standard star data. In companion posters, we describe both the hardware used to obtain the data (J. Brinkmann et al.) and the data themselves (J.A. Smith et al.).
