PHD2 Stops Abruptly when running with SGP

[Jerry Hulm]

Been using PHD2 for quite a while.  Recently switched to a new guide camera.  PHD2 seems to guide fine when I control it myself.  When running a sequence in SGP, PHD2 stops.  I reviewed the log file and there is abrupt stop after this point:

19:04:57.505 00.002 5876 Star::Find returns 1 (0), X=422.06, Y=244.64, Mass=61379, SNR=170.7, Peak=5281 HFD=3.9.

I cannot determine by looking at the log file what happened.  Here is the log file.

The stop point is here:

19:04:58.018 00.005 5876 PhdController failed: Guiding stopped

Would appreciate any help in resolving this.

Thanks,

Jerry

Hi Jerry, thanks for taking a stab at analyzing this yourself.  You can see you got off to a poor start on this particular guiding session:

 

 

The bottom line is that SGP stopped guiding before settling was complete.  To analyze these application interactions with PHD2, you can open the PHD2 debug log file and do a text search on "evsrv".  Here's a reduced and annotated summary of what was going on during thisi period:

 

------------------SGP starts guiding with various settling parameters:
19:03:55.635 00.098 5876 evsrv: cli 0DD0CB38 request: {"method":"guide","params":[{"pixels":1,"time":10,"timeout":600},false],"id":1003}
19:03:55.648 00.002 5876 evsrv: cli 0DD0CB38 response: {"jsonrpc":"2.0","result":0,"id":1003}
------------------Guiding is started and settling status messages are being sent to SGP:
19:03:55.686 00.038 5876 evsrv: cli 0DD0CB38 request: {"method":"get_app_state","id":1001}
19:03:55.690 00.002 5876 evsrv: cli 0DD0CB38 response: {"jsonrpc":"2.0","result":"LostLock","id":1001}
19:03:57.717 00.004 5876 evsrv: {"Event":"Settling","Timestamp":1641693837.717,"Host":"ASTRO-MINI-PC","Inst":1,"Distance":19.87,"Time":0.0,"SettleTime":10.0,"StarLocked":true}
19:04:02.079 00.003 5876 evsrv: {"Event":"Settling","Timestamp":1641693842.079,"Host":"ASTRO-MINI-PC","Inst":1,"Distance":16.87,"Time":0.0,"SettleTime":10.0,"StarLocked":true}

-------------  Approximately 15 more settling messages in here -----------------------------------
19:04:57.569 00.002 5876 evsrv: {"Event":"Settling","Timestamp":1641693897.569,"Host":"ASTRO-MINI-PC","Inst":1,"Distance":1.17,"Time":0.0,"SettleTime":10.0,"StarLocked":true}
-----------------SGP polls PHD2 for status:
19:04:57.577 00.002 5876 evsrv: cli 0DD0CB38 request: {"method":"get_app_state","id":1001}
19:04:57.580 00.002 5876 evsrv: cli 0DD0CB38 response: {"jsonrpc":"2.0","result":"Guiding","id":1001}
-----------------SGP sends a command to stop guiding:
19:04:57.723 00.057 5876 evsrv: cli 0DD0CB38 request: {"method":"stop_capture","id":1004}
19:04:57.731 00.004 5876 evsrv: cli 0DD0CB38 response: {"jsonrpc":"2.0","result":0,"id":1004}

 

I don't know why SGP pulled the plug on this, that was a decision made by the app.

 

Regards,

Bruce
