CD9 tasks (copy of email)

Here's a copy of the email I sent this morning to Mark and Andreas regarding CD9 tasks. -mjr

Now that we're done with CD9 and the data are transferred, we should
talk about the analysis. I've already got Jesse working on the CD8
mapping of the central wavenumber compared to grating resistance, so
I'm not going to include him on this email.

As I see it, we did the focus grid in med mode, the focus grid in
hires mode, checking the 7.4 micron filter for leaks, looking for the
glint, the filter mapping, and the paired pinholes. Anything else?

In dividing these tasks, some are already done, some of us may be busy
with hardware (Mark?), some of us are busy with software (Andreas),
and some of us are parasites..... Anyway, scream if you are unhappy
with this division:

Med mode focus grid - already analyzed for best focus. Could be
looked at in terms of grating parameters since we have so many lines
in a single setting and could check grating equation for each of them
(want to know effective size of pixels, so better worked on after
paired pinholes). Deferred for now.

Hires mode focus grid - already analyzed for best focus. Could be
looked at to properly calculate resolving power, but not going to care
right now since we're over R=100,000. Deferred for now.

7.4 micron filter - no leaks. Done

Glint - gone. Done.

Filter mapping. hires obs of continuum in each and every filter with
echelle spaced 400 ohms. Want to go through and look at each echelle
setting for each filter and evaluate in terms of leaks, relative
throughput, number of orders, spacing between orders, and, eventually,
the central wavenumber (as determined by grating resistance). All
this information will get fed into Andreas's software to help a person
set up an observation. I'm going to take this as my second priority.

Paired pinholes. hires and med mode obs of paired pinholes at
Q-branch. Med mode done at two mirror positions. Analyze for
platescale assuming the pinhole separation is as designed with caveat
that Andreas found the spacing had a jump. I'm going to take this as
my first priority.

In other words, unless you guys are looking for something to do, all
you have to do is keep on me to get these things done. Oh, and keep
yourselves productive for the IRTF readiness review in early Nov.
