Take many frames with same exposure to see sperad of data, error estimate
Take frames with different exposure times, for seeing how varies with exposure time
Finish taking scans of peaks for other lamps
retake halogen spectrum
take some bias frames
Actual Data taking
Cooler temp 5 deg C, started with Helium Lamp
Took 20 frames at exposure time 0.5s, micrometer setting at 6.5mm. This is to investigate whether errors are indeed poisson
Next, took x frames at micrometer setting 6.5mm, starting at 0.1s exposure time, increasing in 0.1s increments. At 3 seconds, increased in increments of 0.5s. Completed data taking at 6s.
Switched to low mercury lamp. Chose 2 spectral lines and took frames of them scanning across the frame.
Peak1: started at 3.4mm, increasing in increments of 0.1mm
Peak2: started at 1.5mm, increasing in increments of 0.1mm
Switched to halogen lamp. Took frames of full spectrum, exposure time of 0.1s, starting at 0.0mm, increasing in 0.5mm increments
Took 2 bias frames
Took 2 dark frames at 0.1s, took 2 dark frames at 0.5s
