本文报道了49个帕洛马巡天视场中437颗恒星的BVR光电测光和位置。本文导出了约翰逊BVR测光与帕洛马底片上的E、O照相星等之间的关系。给出了所有序列星的BVR光度、E和O星等、1950年位置和发现图。大小直径关系的蓝色和红色板，其中28个领域。星等-直径关系基本上具有相同的形状，在板块之间零点有小的偏移。这一初步结果表明，一个共同的函数将描述星等直径的关系，为整个帕洛玛巡天时，校正零点的变化。
BVR photoelectric photometry and positions are reported for 437 stars in 49 Palomar Sky Survey fields. A relation is derived between the Johnson BVR photometry and the E and O photographic magnitudes on the Palomar plates. The BVR photometry, the E and O magnitudes, the 1950 positions and finding charts for all the sequence stars are presented. Magnitude-diameter relations are derived for the blue and red plates for 28 of these fields. The magnitude-diameter relations have essentially the same shape with small shifts in zero point from plate to plate. This preliminary results suggests that a common function will describe the magnitude-diameter relation for the entire Palomar Sky Survey when corrected for variations in zero point.
