Pan-STARRS Photometric and Astrometric Calibration

“…DR1 contains the results of the third full reduction of the Pan-STARRS 3πSurvey archival data, identified as PV3. Previous reductions (PV0, PV1, and PV2; see Magnier et al 2020a) were used internally for pipeline optimization and the Magnier et al (2020b, Paper IV) describes the details of the source detection and photometry, including point-spreadfunction (PSF) and extended source fitting models, and the techniques for "forced" photometry measurements. Flewelling et al (2020, Paper VI) describes the details of the resulting catalog data and its organization in the Pan-STARRS database.…”

Pan-STARRS Pixel Processing: Detrending, Warping, Stacking

“…DR1 contains the results of the third full reduction of the Pan-STARRS 3π Survey archival data, identified as PV3. Previous reductions (PV0, PV1, PV2; see Magnier et al 2020a) were used internally for pipeline optimization and the development of the initial photometric and astrometric reference catalog (Magnier et al 2020b). The products from these reductions were not publicly released but have been used to produce a wide range of scientific papers from the Pan-STARRS1 Science Consortium members (Chambers et al 2017).…”

“…A new photometry analysis package was developed using lessons learned from the existing photometry systems. In the process, the source analysis software was written using the data analysis C-code library written for the IPP, psLib (Magnier et al 2020a). Components of the photometry code were integrated into the IPP's midlevel astronomy data analysis toolkit called psModules (Magnier et al 2020a).…”

“…In the process, the source analysis software was written using the data analysis C-code library written for the IPP, psLib (Magnier et al 2020a). Components of the photometry code were integrated into the IPP's midlevel astronomy data analysis toolkit called psModules (Magnier et al 2020a). The resulting software, "psphot," can be used either as a standalone C program or as a set of library functions that may be integrated into other programs Several variants of psphot have been used in the PS1 PV3 analysis.…”
