Change' for the sake of change. A monospaced style "let's you go free" with stuff. A terrible list of wiki formatting crap is at the link ​https://trac.edgewall.org/wiki/WikiFormatting. It is good that this all different from html. One should use html10.3.17, cause html10.3.16 is so 3 weeks ago.

Scripts and Methods where a "Quick Link" page to the wiki would be useful. IT CUURENTLY HAS ONE Link.

Here is a link When do I run autotwi.py

When do I run autotwi.py for morning skyflats? Answer.

• autotwi.py is a useful script for taking HPF, LRS2 and VIRUS skyflats. It has a clear and extensive usage mesaage, but some useful extra information is below.

 Start the autotwi script in the  morning when the raw gc2 flux level is around 2.7k adu. 
 Start the autotwi script in the  evening 4min before sunset (if taking HPF flats).
 Start the autotwi script in the  evening after the dome is open and ready for flats with the raw gc2 flux higher than 45K adu (if taking LRS2/ and VIRUS flats).

* What is netsound.sh and how do I run it?

This script gives audible warnings when the hpf looses connection with timshet.

  [sco@zeus ~]$ ssh -R 10002:localhost:10001 hpf@hpf
  [sco@zeus ~]$ /home/mcs/sir/dev/astro/trunk/operations/netsound.sh

1) There are notes about doing "ssh -R 10002:localhost:10001 hpf@hpf" on zeus.

Maybe I have been lucky and just never had a timshet fail, but I have never heard anything from this. Maybe there is some key thing I am missing.

* When a modbus failure occurs, what do I do?

Here are my personal notes:

1) kill the "at" job with atq, atrm

2) kil remaining cal jobs (on zeus) with:

% ps -e |grep cal % kill -9

3) Restart pfip server, restart cals as "at" jobs.

Is there a better wiki resource? Just a Yes!/No will do.

I have no personal notes. I just try stuff.
