Data collected in Miami after Hawaii-2016-02 data collection in Hawaii. The Resonon tubing was loose once it arrived in Miami but there was no damage.
Problems seen (and solved):

Hi Steph, I know you are dealing with the MOS data today but Ken and I were trying out some basic data acquisition with the BS and I wanted to send you some files for whenever you have a chance. Good news is that there is a slick one line function in the andor sdk to save a scan as a fits file. It writes all the keywords Mike has been using (it must be the same underlying function that is in SOLIS). We captured a few images if you want to try them. Use sftp into optilab and then in the directory /home/moby3/tmp/testfits160419 There are these files: image101.fits: Hg(A) lamp, 0.1 sec integration time image102.fits: Hg(A) lamp, 1.0 sec integration time image103.fits: sunlight, 0.1 sec integration time image104.fits: sunlight, 0.5 sec integration time image105.fits: dark, 0.1 sec integration time image106.fits: dark, 0.5 sec integration time A few notes on these files: 1. I saved as 32 bit integers by accident. But there is a 16 bit option I should have used/will use for next time. 2. the "dark" files above were actually taken with the shutter open but with a cover over the fiber ends, so not really a dark from the camera perspective. The bad news is that because the function is so canned, I haven't found a way to insert our own comments (things you were mentioning like which fiber shutters were open). There may or may not be a way to do that (e.g. by adding keywords) but I haven't found an easy way yet. Also, it seems this canned routine is one image per file, so each scan would have a corresponding fits file, which will have some plusses and minuses relative to a format with say dark, light, dark all in one file. For the same reason, it's not as easy to write a fits file for data we've processed on board. I think if I do the binning on camera it should probably write the fits just fine (we can test that assumption). But if I read a whole image then average myself I doubt it will write those averages to a file with this nice simple function. There is a fits library I can download to be able to add some of this functionality, but worth some discussion at this point if we want to stick with fits or not before I start down that road. Art Stephanie's notes: I renamed the files to match Mikes filenaming convention so my automated programs would work. There are these files new names: image101.fits: s2016041901.fits image102.fits: s2016041902.fits image103.fits: s2016041903.fits image104.fits: s2016041904.fits image105.fits: b2016041901.fits imagexxx.fits: b2016041902.fits - no 1 sec dark file exists image105.fits: b2016041903.fits image106.fits: b2016041904.fits |

Something is way wrong, either the set up in Miami had no UV flux (different tile, glass in the optical train, …) or the BS has changed. This is a significant change in the relative spectral distribution.
carol HI Carol, I wouldn’t worry about it….like I said, this was a quick check…I looked through the window of my lab (probably double paned)…..it was just to get a quick check of the fraunhofer lines.
I am afraid to work the system outside, until I figure out why the spec leaks air….
ken By the way….Art reminded me that for some of our measurements, because I wanted to keep the signal low and integration time reasonable, we made them with the plastic protective caps on the end of the fiber tips…… Ken
