![]() ![]() 2019.02.25: ForcedMeanObject and ForcedMeanLensing tables available 2019.12.11: Easy cross-match using the MAST catalogs APIĪ new web page, Easy cross-match with PS1 using a list of source positions, shows that it is very simple to cross-match a list of positions to the PS1 catalog using a single curl command or a simple Python script. That is substantially reduced from the missing area at the time of the DR2 release. Currently about 4.9 square degrees (only 0.016%) of the sky has missing objects. The PS1 DR2 caveats page's description of sky regions with missing data in the PS1 database has been updated. 2020.06.29: Missing data sky regions updated See the How to retrieve and use PS1 data page for additional information, including a link to a Python Jupyter notebook. It provides an alternative to CasJobs for SQL queries of the database. ![]() PS1 has a Virtual Observatory-compatible Table Access Protocol (TAP) interface for the PS1 database. 2020.06.29: PS1 VO Table Access Protocol information added 2021.11.04: Bulk image download Python scriptĪ Python script that does faster bulk cutout image downloads from a list of RA and Dec positions has been added to the PS1 Image Cutout Service page. See PS1 Astrometry Correction Using Gaia EDR3 for more details. It is still possible to access the old positions, but the new astrometry is preferred for most purposes. Systematic astrometric distortions and color terms (from differential chromatic aberration) are greatly reduced. The astrometry in PS1 has been updated using Gaia EDR3. 2022.06.30: PS1 astrometry updated using Gaia EDR3 ![]()
