Source Extraction for TESS Full Frame Images

Project description

eleanor is a python package to extract target pixel files from TESS Full Frame Images and produce systematics-corrected light curves for any star observed by the TESS mission. In its simplest form, eleanor takes a TIC ID, a Gaia source ID, or (RA, Dec) coordinates of a star observed by TESS and returns, as a single object, a light curve and accompanying target pixel data.

Changes to v2.0.2 (2021-02-05): * Fixed bugs in setting download directory paths * Fixed bugs for Windows users * Other minor bug fixes

Changes to v2.0.1 (2020-12-08): * Minor bug fixes

Changes to v2.0.0rc1 (2020-10-05): * Changing skip parameter in correction to be in unit of time rather than cadences to handle 10-minute FFIs * Fixed bug where very faint stars had suboptimal corrections * Changed crowded_field to aperture_mode and added built-in mechanics for bright stars * Updated docs to include citation to 2019 paper * Fixed bug in eleanor.Visualize() layout of aperture * Changes to handle format of 10-minute FFIs in eleanor.Update() * Significant speedups, especially when local postcards already exist and run with local==True * Other bug fixes

Changes to v1.0.5 (2020-05-21): * Fixed bug where some apertures were made twice and others not at all * Fixed bug where mass centroids were off by a constant offset at all cadences * Fixed bug that happens when data are all zeros at the start of a sector

Changes to v1.0.4 (2020-03-27): * Pass in an array of regressors to use in calculating the corrected flux * Extreme short-term flux variability like eclipses ignored in corrections, which should improve detrending of these objects * Fixed bug where metadata could not be properly updated on linux clusters * Improvements to Gaia overlay of fields * Ability to create light curves offline * Ability to pass through a SIMBAD-resolvable name rather than TIC/Gaia ID or coordinates * Other minor bug fixes

Changes to v1.0.1 (2019-12-19): * Ability to use local postcards * Addition of eleanor.Update() for automatic sector updates * Significant speedups when TIC, Coords, and a Gaia ID are all provided * Other bug fixes

Changes to v1.0.0 (2020-01-14): * Pass in the name of the source as a string * Other bugfixes
