Webphotometric system [14], and most recently with the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) [17] [18]. Both of these surveys use what is generally referred to as the Sloan photometric system, although individual differences exist between the filters used by SDSS and those used by Pan-STARRS [17]. WebAug 4, 2024 · However, before the image conversion, the various bands of the SDSS photometric data are not aligned. This is because the CCD camera of SDSS survey telescope corresponding to different filters will not be exposed at the same time when the photometric image is taken, which leads to each photometric image has a deviation of …
