While the code description says that detx, and dety are in units of radians, it seems that they are actually in units of degree.

Example:
<pre>
cta = GCTAObservation()
cta.load('run_0023592_std_eventlist.fits')
events = GCTAEventList(cta.events())
event = events[0]
detx = event.dir().detx()
dety = event.dir().dety()

In [57]: detx
Out[57]: 0.3536582589149475

In [58]: dety
Out[58]: -0.01053939200937748
</pre>
