cdf2df

heliopy.data.util.cdf2df(cdf, index_key, dtimeindex=True, badvalues=None, ignore=None, include=None)

Converts a cdf file to a pandas dataframe.

Note that this only works for 1 dimensional data, other data such as distribution functions or pitch angles will not work properly.

Parameters

  • cdf (cdf) – Opened CDF file.

  • index_key (str) – The CDF key to use as the index in the output DataFrame.

  • dtimeindex (bool) – If True, the DataFrame index is parsed as a datetime. Default is True.

  • badvalues (dict, list) – Deprecated.

  • ignore (list) – In case a CDF file has columns that are unused / not required, then the column names can be passed as a list into the function.

  • include (str, list) – If only specific columns of a CDF file are desired, then the column names can be passed as a list into the function. Should not be used with ignore.

Returns

df – Data frame with read in data.
