Lab data from UT250425

Data taken just preceding spectrograph disassembly in lab. Data from calibration source taken both directly with 50 micron fiber and through calibration channel. Solar data through long (poor throughput) 200 micron fiber.

Flats (LED+tungsten with and without iodine):

Results from lab testing UT250416

eShel calibration source connected directly to spectrograph input with 50 micron fiber because of issues with long eShel 200 micron fiber (which was very faint). Also removed beam splitters to increase throughput.

Long eShel fiber was used to collect sunlight from outside into the building lobby with a mirror, then fed into calibration channel, which feeds a 50 micron fiber in the Shelyak FIGU unit that connects to spectrograph input.
