class edge_pydb.EdgeTable(file='', path='', cols=None, data=None, masked=None, names=None, dtype=None, meta=None, copy=True, rows=None, copy_indices=True, **kwargs)

Bases: Table

Definition of the EdgeTable class. An EdgeTable is a regular Astropy table in either ECSV or HDF5 format.

Parameters:

filestr

Name of the file. This is generally NOT a full path, as the package maintains a list of available tables. The name should end with .csv or .hdf5. Use ‘list’ to provide a listing of available tables.

pathstr

Name of the path within the file, for HDF5 files only. If not given, a list of available paths is output.

colslist of str

A list of columns to read in. Other columns are discarded.

Methods Summary

join(table[, join_type, keys])
read(file[, path])	Read and parse a data table and return as a Table.

Methods Documentation

join(table, join_type='inner', keys=None)

read(file, path='')

Read and parse a data table and return as a Table.

This function provides the Table interface to the astropy unified I/O layer. This allows easily reading a file in many supported data formats using syntax such as:

>>> from astropy.table import Table
>>> dat = Table.read('table.dat', format='ascii')
>>> events = Table.read('events.fits', format='fits')

Get help on the available readers for Table using the``help()`` method:

>>> Table.read.help()  # Get help reading Table and list supported formats
>>> Table.read.help('fits')  # Get detailed help on Table FITS reader
>>> Table.read.list_formats()  # Print list of available formats
