units of sky maps

[silviacaprioli]

Hi!
I'm starting to learn how to use PySM. I just created a sky object:

sky_config = {
'dust' : models('d1', nside),
'synchrotron' : models('s1', nside),
 'ame' : models('a1', nside),
'freefree' : models('f1', nside),
'cmb' : models('c1', nside)
}

and then:

sky = pysm.Sky(skyconfig)
T, Q, U = sky.signal(nu=43)

it's probably a trivial question, but it's not clear to me which are the units of T, Q and U.
It's u_K_RJ? or u_K_CMB? or something else?
I read the documentation but I couldn't find this information explicitly reported anywhere.

Thank you in advance!
