Methods Documentation

async cmd_evt_connect_callback(server)#

Callback function for when a cmd/evt client connects or disconnects.

When a cmd/evt client connects, background tasks are started and events are sent. When the cmd/evt client disconnects, all background tasks get stopped.

Parameters:

server (OneClientServer)

Return type:

None

Set configuration.

Parameters:

  • m1_covers_close_time (float) – Time to close M1 mirror covers [sec].

  • m1_covers_open_time (float) – Time to open M1 mirror covers [sec].

  • cell_vents_close_time (float) – Time to close cell vents [sec].

  • cell_vents_open_time (float) – Time to open cell vents [sec].

  • m1_pressure (float) – Initial M1 air pressure [Pa].
