return_units(self, data_type)

Function for returning a string representing the parameters units.

For example, the internal representation of te is in seconds, whereas the external representation is in picoseconds, therefore this function will return the string 'picoseconds' for te.

set(self, run=None, value=None, error=None, data_type=None, index=None)

Reduced spectral density mapping set details
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In reduced spectral density mapping, only two values can be set, the bond length and CSA
value.  These must be set prior to the calculation of spectral density values.
