 Build coefficient of performance (COP) time series for air- or ground-sourced
 heat pumps.
 
-The COP is approximated as a quatratic function of the temperature difference between source and
-sink, based on Staffell et al. 2012.
+For individual (decentral) heat pumps, the COP is approximated as a quatratic function of the temperature difference between source and sink, based on Staffell et al. 2012.
+For district (central) heating, the COP is approximated based on Jensen et al. 2018 and parameters from Pieper et al. 2020.
