get_table_data¶

gunagala.utils.get_table_data(data_table, column_names, column_units, data_dir='data/performance_data', **kwargs)[source]¶

Parses a data table to extract specified columns, converted to Quantity with specified units.

Parameters:

data_table: astropy.table.Table or str: The data table for parsing, either as an astropy.table.Table object or the name of a file that can be read by astropy.table.Table.read(). The filename can be either the path to a user file or the name of one of gunagala’s included files.
column_names: sequence: Names of the columns to extract from the table
column_units: sequence: Desired units for the extracted columns. If data_table specifies units for its columns then the extracted columns will be converted to these units. If not then the specified units will be added to the corresponding column.
Additional keyword arguments will be passed to the call to astropy.table.Table.read()
if reading a Table from a file. See the documentation for Table.read() for details
of the available parameters.

Returns:

data: tuple of astropy.units.Quantity: Tuple of Quantity objects corresponding to the named columns, with the specified units.
