• We initially took images of the quasar to locate it, the spectrograph was then places in front of the CCD to obtain its spectrum. * As 3c273 is an object with a magnitude of 12.9, many frames were taken to try and increase the signal to noise.
  • This is a single frame of 3c273 and its surrounding stars,
  • 3c273_Spec_1_Image.jpg.png:
  • This is then a stacked image of 30 frames with 3c273 highlighted:
  • Full_Bin2_Image.jpg.png:

  • The area highlighted on the plot was sliced from the array, and an area just above was also sliced to be used as the background.
  • The plot below shows the initial slice without the zeroth order star, the background slice and the slice with the background subtracted,
  • Slices.png:
  • The final slice was the projected onto the x axis:

  • The first image shows 10 frames stacked:
  • 3c273_2.png:
  • The second image shows all 30 frames stacked:
