- Docs describing how to set up the AO system on-sky, prior to starting science observations

Thanks for this, @jlibermann. It looks like something funky happened with index.rst. It could be windows line endings. Could you correct that so the only edited lines are the one you actually added? |

Great job @jlibermann. A few details to clean up. I think we want to reorganize a little to add an alignment procedure, based on the one I put on slack and is pinned, as a separate thing that happens before acquisition and loop-closing. You can get higher quality figures for the guis using your remote operations ability and screen-shotting them.

| * Set the FPS on the ``camwfsctrl`` GUI to ``2000`` | ||
| * In CursesINDI, type ``fxngensync`` and toggle the state to ``On`` (see the `cursesINDI guide <./software/guis/cursesINDI>`__ if you need a refresher) |

| #. In the web interface, set ``fwpupil`` to ``bump-mask``. | ||
| #. Now use the ``Pupil Plane`` buttons in the ``coronAlignGUI`` to align the bump mask on the pupil. Set the step size to ``100`` and press the down arrow 3 times. This is typically enough to align the bump mask. However, if the bump mask still appears slightly misaligned, reduce the step size to ``5`` and use the left/right arrow keys for fine adjustments. |

this is correct, but assumes that the alignment was already done on the soruce to get the mask close. just re-making the point that we need a separate alignment procedure (like the one that is pinned on slack)

| Closing the Pupil Alignment Loop | ||
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ||
|
|
||
| #. In the ``Pupil Alignment`` GUI, use the keypad in the lower-righthand corner to drive the x and y avg values to 0. After each translation, wait a few seconds for the readings to stabilize. Also note that the x-axis is much more sensitive than the y-axis. When moving x-axis avg to 0, use step sizes of about 0.1. When moving y-axis to 0, higher step sizes can be used. |

the idea is correct. It's really something like "when x is within 0.2, steps sizes of 0.05 should be used. The y-axis steps size can remain 0.1"

change "roughly 0" to "0 +/- 0.1"
…rman/handbook into onsky-operation-docs

What's going on here? It looks like a lot more changes and some regressions (introducing old typos etc)? |
