[Radiance-general] unit of irradiance using epw as input

Hi, may I ask if the unit of irradiance is *Wh/m2* if I use the "epw
weather file + gendaylit/gencumulativesky + rtrace" method to get the
irradiance of a given point for a particular hour in a year or annual total
irradiance?

The three radiation variables in epw file are using the unit of Wh/m2, so I
assume the output of rtrace simulation using epw file as input should have
the same unit. Is it correct?

Thanks!
