No. It's radiant flux of the signal.

----------------
Mount coordinates - what does it mean?
Coordinates of telescope mounting
----------------
Mount init. - what does it mean?

----------------
Park - that one I understand but it seems it is used both as noun and verb (at least I see in my telescope simulator on Main control tab two "Park", one as control and other one as button) which makes translation hard ...
Yes. The translation is hard thing to do... :'(
-----------------
Position - where is it? Translation may be dependent of exact use.
Position of the focuser.
Set register - is it a command? And what exactly is "register" here?

Save home - is it a command? And what does "home" mean here?

app., refr., tel., observed - what does it mean, or rather for what is it used?
app., refr., telescope - what does it mean, or rather for what is it used?
Apparent to observed coordinates transformation and the modes of this transformation using libnova.
-----------------
Use Pulse Cmd - what does it mean?
Use pulse-guide commands. Set to on if this mount can support pulse guide commands. There appears to be no way to query this information from the mount.
------------------
danger - what is it?
Master alarm option ("off", "danger", "ON", "reset")
------------------
rel. to HA - I understand it is "relative to hourangle" but where is it used?
Mount declination axis position relative to HA coordinates.

Hope this helps.
