MockDomeController

class lsst.ts.ATDome.MockDomeController(port, door_time=1, az_vel=6, home_az=10, home_az_overshoot=1, home_az_vel=1)

Bases: object

Mock DomeController that talks over TCP/IP.

Parameters:
port : int

TCP/IP port. If 0 then pick an available port.

door_time : float

Time to open or close either door (sec)

az_vel : float

Azimuth velocity (deg/sec)

home_az : float

Azimuth home position (deg)

home_az_overshoot : float

Distance to move CCW past the home switch at full speed while homing, before coming back slowly (deg)

home_az_vel : float

Final velocity for azimuth homing, once the home switch has been contacted at full speed (deg/sec)

Notes

To start the server:

ctrl = MockDomeController(…) await ctrl.start()

To stop the server:

await ctrl.stop()

Known Limitations:

  • The following commands are not supported: AO, AF, RO, RF, CO, CF, TOL, HZ, HS, CS, LM, WT, RD, CFS, CFR, HELP
  • Encoder counts are not supported; reported values are bogus.
  • Door sequencing is not supported; doors move as if independent.
