The Pan-STARRS1 (PS1) Science Consortium has carried out a set of imaging surveys using the 1.4 gigapixel GPC1 camera on the PS1 telescope. As this camera is composed of many individual electronic readouts and covers a very large field of view, great care was taken to ensure that the many instrumental effects were corrected to produce the most uniform detector response possible. We present the image-detrending steps used as part of the processing of the data contained within the public release of Pan-STARRS1 Data Release 1 (DR1). In addition to the single image processing, the methods used to transform the 375,573 individual exposures into a common sky-oriented grid are discussed, as well as those used to produce both the image stack and difference combination products.

Pan-STARRS 像素处理:去趋势、变形、堆叠

Pan-STARRS1 (PS1) 科学联盟使用 PS1 望远镜上的 1.4 吉像素 GPC1 相机进行了一系列成像调查。由于该相机由许多单独的电子读数组成并覆盖了非常大的视野,因此非常小心地确保校正许多仪器效应,以产生尽可能均匀的探测器响应。我们介绍了用于处理 Pan-STARRS1 数据版本 1 (DR1) 公开发布中包含的数据的一部分的图像去趋势步骤。除了单幅图像处理之外,还讨论了用于将 375,573 次单独曝光转换为公共面向天空的网格的方法,以及用于生成图像堆栈和差异组合产品的方法。
