Quality assurance relative transparency plots for mmirs_qrp #7

Open astrochun opened 6 years ago

astrochun commented 6 years ago

Using the differenced images, integrate the flux around bright target if available. Then compare these 1-D spectra to get relative transparency to the best image. Finally plot the relative transparency vs the exposure number.

Began implementation with bright = True in 0494f7d. Need to normalize by exposure time and make sure the background subtraction is at zero.

Exposure time normalization done in 9281e71. Plotting improvements done in b240bd9, cdd89a1, 66c25ee. Array containing total counts is normalized to unity for reference.

Difficulty in background subtraction stems from using A-B difference images. We will need to avoid the region with the negative source.
