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.
