TL;DR
This paper introduces a network of 158 standard stars that establish the u'g'r'i'z' photometric system, crucial for calibrating the Sloan Digital Sky Survey and related astronomical observations.
Contribution
It details the creation and validation of a standard star network for the u'g'r'i'z' system, including methods, software, and transformation equations from other systems.
Findings
Defined 158 standard stars for u'g'r'i'z' system
Established calibration procedures for SDSS
Provided transformation equations for UBVRcIc system
Abstract
We present the 158 standard stars that define the u'g'r'i'z' photometric system. These stars form the basis for the photometric calibration of the Sloan Digital Sky Survey (SDSS). The defining instrument system and filters, the observing process, the reduction techniques, and the software used to create the stellar network are all described. We briefly discuss the history of the star selection process, the derivation of a set of transformation equations for the UBVRcIc system, and plans for future work.
