Observing Summary:

Realized part way through the night that the headers of
all the files over the past couple nights have been
recorded wrong. Specifically, the IDs of the slit, both
filters, and the disperser, while the position of these
wheels was correctly recorded. I closed out of Prospero
and reopened it and that seemed to do the trick. Had to
go back and edit the headers. Couldn't really figure out
why this happened in the first place, but it seems to be
fine now.

I also had trouble with a lack of signal when gathering
spectra. At some point in the night (in the middle of
a series of spectra of one object) it seems as though
I lost the object, even though the telescope seemed to 
be tracking fine, and I hadn't made any changes to the
exposure settings in between exposures. From this point on,
there were several objects for which I would be aligned
according to osctrtask, but I would get no signal. I even
tried bumping up the exposure time significantly just to
be sure I was getting the counts, but to no avail. I'll 
have to think on this further...

No other software or mechanical issues.
