Seechange Tools 1.0.0

This is a collection of tools that were used in the execution of the See Change Supernova a Survey, a 178 orbit HST program to discover and characterize type Ia supernovae above redshift 1.1. Included are scripts to aid in orbit planning when the chosen filter may be affected by elevated background levels, a precision alignment routine to aid in designing accurate masks for ground-based multi-object spectroscopy, and a weighted cross-correlation routine for robust redshift determination from spectra taken at any variety of facilities.
