 === 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.
+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, using a mirror to reflect sunlight onto the fiber tip (in the building lobby).
+Note that we discovered after the fact that only one channel of the heater for the iodine cell was functioning, so while one half was set to and reading 60C, the other half was only reading ~42C.
 Flats (LED+tungsten with and without iodine) and solar (w/ and w/o iodine):
