Over 3 billion astronomical sources have been detected in the more than 22 million orthogonal transfer CCD images obtained as part of the Pan-STARRS1 3π survey. Over 85 billion instances of those sources have been automatically detected and characterized by the Pan-STARRS Image Processing Pipeline photometry software, psphot. This fast, automatic, and reliable software was developed for the Pan-STARRS project but is easily adaptable to images from other telescopes. We describe the analysis of the astronomical sources by psphot in general as well as for the specific case of the third processing version used for the first two public releases of the Pan-STARRS 3π Survey data.

Pan-STARRS 像素分析:源检测和表征
在作为 Pan-STARRS1 3 π调查的一部分获得的超过 2200 万张正交传输 CCD 图像中,已经检测到超过 30 亿个天文源。Pan-STARRS 图像处理管道测光软件psphot已自动检测并表征了这些来源的超过 850 亿个实例。这种快速、自动且可靠的软件是为 Pan-STARRS 项目开发的,但很容易适应其他望远镜的图像。我们描述了psphot对天文来源的一般分析以及用于 Pan-STARRS 3 π调查数据的前两次公开发布的第三个处理版本的具体情况。
