content of the file daily_heat_demand_total_base_s_{clusters}.nc produced by the rule build_daily_heat_demand ?

Dear Pypsa developers, 

I would be grateful if someone could enlighten me on the content of the file 

daily_heat_demand_total_base_s_{clusters}.nc 

produced by the rule build_daily_heat_demand 

I just wanted to run the rules that provide the daily heat demand for selected countries but the output I get contains numbers that do not make sense to me, they are much higher then the heating load stored in the network constructor (n.loads_t), the units are supposedly MW but it doesn't look so. Unfortunately I could not find any documentation to answer my questions. 

Thank you very much, 

Cecilia
