Data to be taken

• 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
