PS water vapor analysis, Nov 2014
I have written a code that runs through a directory of fits files, isolates the spectrum of Polaris, and performs PWV analysis on it.
This is a set of what some of the typical spectra look like in the data set:
- I consider this a "good" image. Spectrum is there in full, and in focus. Note that I have the absorption features highlighted as well (O2 A, O2 B, and four H2O features). This fits image is median-subtracted, meaning I just took the raw median of the whole image and subtracted it.
- This is an image where the filter wheel has the spectrum "chopped up", making it not useful for analysis of absorption features.
