Reproducing "The Nearby Evolved Stars Survey: I. JCMT/SCUBA-2Sub-millimetre detection of the detached shell of UAntliae" paper by Thavisha E. Dharmawardena, et al., subm. MNRAS.

A full description of the methods used is provided in Secs. 2 and 3 in the paper.

Generated using python3.6 (suitable for python2.7 and later versions)

Steps followed:

1. Data Download and Reduction
2. Radial profile generation and plotting
3. Aperture Photometry
4. Generating images of the SCUBA-2 and HARP observations
5. Radial point-to-point SED fitting and determining Temperature, Density and Beta profiles using EMCEE
6. Calculating mass-loss from the Density profiles
7. Raditative transfer modelling using Hyperion

For testing the differences between the CO-subtracted and Non-CO-subtracted SCUBA-2 850micron observations replace the CO-subtracted .fits file with the non-CO-subtracted .fits file and use the same code.
