Kampylos binary-lens grid search: MOA-2002-BLG-031
收藏资源简介:
Kampylos is a volunteer-computing search run by BitBOINC (https://bitboinc.athena.org.tr) that re-analyses archival gravitational microlensing photometry for binary-lens and other unusual signals that a single-lens fit would miss. This record is the complete raw grid-search output for MOA-2002-BLG-031, a 2002 MOA event: for every cell of the (separation s, mass ratio q) grid, the best chi-squared and the full fitted parameter set (t0, u0, tE, alpha, rho, fs, fb) after a local optimisation of the other five parameters. Columns are documented in the file's header lines. The grid covers log10(s) from -1 to 1 (11 values) and log10(q) from -5 to 0 (10 values), 110 cells; best cell: log10 s = 0.400, log10 q = -0.556, with delta-chi2 = 235.1 relative to the best single-lens fit to the same data. This is raw search output; no significance is claimed. Input photometry is not included; it is MOA's public survey data (https://moaprime.massey.ac.nz/moaarchive). Computed by 16 volunteers (84 validated results) on BitBOINC. Volunteers who asked to be named: Anand Bhat (Australia), Dejan Ivanek (Croatia), Detlef Lexut (Germany), Erik Veit (United States), Frederik Schiøler (Denmark), Frolov Kirill (Russia), Jörg Steinmetz (Germany), José Miguel (Spain), jozef janoska (Slovakia), Kyle Weber (International), Michael Doneske (United States), Peimao Jiang (China), Robert M Andrews (United States), Yevhen Vasiliu (Ukraine); and 2 other volunteers. Thank you.
