This repo provides the tools necessary to reproject a 2-dimensional set of colours using the reddening curve projection described in Fraser et al. (under review). In summary, the colours are reprojected to two new components: the perpendicular distance from the reddening curve to the point defined by the colours, and the line integral along the reddening curve to that point from a reference colour (usually the Solar colour).
The module contains an array which tabulates the Col-OSSOS colours (u-g), (g-r), (r-i), and (r-J), and the H/WTSOSS colours (F606w-F814w), (F814w-F139m), and (F139m-F153m) for spectral slopes -6 <= s <= 73 %/100 nm normalized at 550 nm. The user can provide arrays for other colours or filter systems.
To do:
- remove the Col-OSSOS specific code in main
- include a very basic example of how to use
- update this readme with the example
