Thanks for catching this @gterreran! Can you please let us know how you tested this PR and what we should do to test it? |

I asked Megan to test it by trying to do an image subtraction with PS1. You can probably do the same. |

@gterreran you are much more familiar with the problem, what looks wrong, and what looks right. Please provide a detailed test plan (e.g. what commands to run and how to tell if the bug is fixed from the output). PR #132 has an example. |

When the noise image was created, a few missing gain factor were missing.
Since the noise image is created at least in two instances, I created a separate function. I also added some comments to make it more readable.
The gain for Sinistro should be 1, so even with this bug, previous LCO-LCO subtractions should not have been affected. However subtraction using other surveys might have.
