M.P.E.C. 2023-P03 Issued 2023 August 1, 22:01 UT The Minor Planet Electronic Circulars contain information on unusual minor planets, routine data on comets and natural satellites, and occasional editorial announcements. They are published on behalf of Division F of the International Astronomical Union by the Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. Prepared using the Tamkin Foundation Computer Network MPC@CFA.HARVARD.EDU URL https://www.minorplanetcenter.net/ ISSN 1523-6714 EDITORIAL NOTICE: DIGEST2 UPDATES The Minor Planet Center (MPC) is announcing an update to the configuration file and the population model of the "digest2" code used for scoring tracklets submitted to the NEOCP (Near-Earth Object Confirmation Page). Tracklets with digest2 scores greater than 65 are eligible to be posted to the NEOCP. These updates will become operational on Friday, August 4th, at 14:00 UTC. The MPC updates the population model (digest2.model.csv) to align with the current completeness of the discovered minor planets, which stands at 1.3 million orbits. In recent years, the updates have become more frequent due to the rapid increase in the number of discovered objects, thanks to the dedicated efforts of large surveys. We expect the updates to become even more frequent when the Vera Rubin Observatory (LSST) and NEO Surveyor commence their operations. Furthermore, the MPC has expanded the configuration file (MPC.config), which now includes a list of 140 observatory codes with assumed uncertainties. These observatory codes are utilized in the computation of the digest2 score, marking a significant expansion from the previous list of only 35 observatories Both files can be downloaded as an archive (d2model.tar.bz2) from https://bitbucket.org/mpcdev/digest2/downloads/ M.
