read_data

tessilator.tessilator.read_data(t_filename, name_is_source_id=0)

Read input data and convert to an astropy table ready for analysis

The input data must be in the form of a comma-separated variable and may take 3 forms:

(a) a 1-column table of source identifiers

(b) a 2-column table of decimal sky coordinates (celestial or galactic)

(c) a pre-prepared table of 5 columns consisting of source_id, ra, dec, parallax, Gmag (without column headers)

Note that a single target can be quickly analysed directly from the command line by using option (a) with double-quotation marks around the source identifier.

E.G. >>> python run_tess_cutouts 0 0 0 files “AB Doradus”

Parameters:

t_filenameastropy.table.Table

name of the file containing the input data

name_is_source_idint, optional, Default=0

when running option (c), this toggle if == 1 will automatically set the “name” column as the Gaia DR3 identifiers. This avoids long sql queries for very large input tables.

Returns:

t_targetsastropy.table.Table

a formatted astropy table ready for further analysis
