# Parsed data (version 1.5)¶

This is a list of all the data parsed by the current official release of cclib (namely version 1.5). For the same list for the development version, see development parsed data. For details and miscellaneous notes on these attributes, see the data notes page.

## Description of parsed data¶

Click the attribute name in the table below to go the notes and specifications for a particular attribute. All arrays are Numpy arrays of type ‘d’ (if containing floats) or ‘i’ (if containing integers).
