conditions can be summed in three states:
1. Ok: Weather conditions are clear and optimal for imaging.
2. Warning: Weather conditions are not clear, seeing is subpar, or partially
obstructed and not suitable for imaging. Any further imaging process is
suspended until the weather improves. Warning weather status does not pose
any danger to the observatory equipment so the observatory is kept
operational. The exact behavior to take under Warning status can be
configured.
3. Alert: Weather conditions are detrimental to the observatory safety and
shutdown must be initiated as soon as possible.
Aborted Job Management
Define what should happen when a job steps into an error or aborts:
· Don't re-schedule (None): Don't restart the job in case of an error or an abort.
· Re-schedule after all terminated (Queue): If a job gets aborted, the scheduler
will only re-schedule it if when all jobs are finished or aborted. If this is the
case, the scheduler re-schedules all aborted jobs and sleeps for the given
delay.
· Re-schedule immediately (Immediate): As soon as a job gets aborted, the
scheduler will re-schedule it and waits the given delay.
If the option for re-scheduling errors is selected, errors are handled like aborts.
Otherwise, jobs that step into an error are never re-scheduled.
Startup & Shutdown Scripts
Due to the uniqueness of each observatory, Ekos enables the user to select
startup and shutdown scripts. The scripts take care of any necessary procedures
that must take place on startup and shutdown stages. On startup, Ekos executes
the startup scripts and only proceeds to the remainder of the startup procedure
(unpark dome/unpark mount) if the script completes successfully. Conversely, the
shutdown procedure begins with parking the mount & dome before executing the
shutdown script as the final procedure.
Startup and shutdown scripts can be written any language that can be executed
on the local machine. It must return 0 to report success, any other exist value is
considered an error indicator. The script's standard output is also directed to
Ekos logger window. The following is an sample demo startup script in Python:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
import time
