Parsed data

From cclib

This is a list of all the data parsed by the current official release of cclib. For the same list for the development version, see development parsed data.

Description of parsed data

Click the attribute name in the table below for the specifications for a particular attribute. All arrays are Numpy arrays of type 'd' (if containing floats) or 'i' (if containing integers).
