Enhanced Numerical Toolkit Enabling Robust PulsaR Inference SuitE. A software package used in detection and some noise analyses. ᴇɴᴛᴇʀᴘʀɪsᴇ is a toolkit providing the pieces needed to construct our models for GW and noise processes. ᴇɴᴛᴇʀᴘʀɪsᴇ constructs likelihood and prior functions that can then be used in Bayesian (or other) data analysis.
