PRIMA: modeling the expected performance of PRIMAger

PRIMA is an actively cooled infrared observatory designed to provide the astrophysics community with mid- to far-infrared coverage from 24–265 µm. Its camera, PRIMAger, features a hyperspectral mode (24–84 µm, R ≈ 8) using an LVF and a polarimetric mode with four broadband, polarization-sensitive filters. We present expected detector performance, NEP estimates, filter and LVF characterization, and optical design simulations, along with observing modes and mapping strategies. These results will guide the community in preparing guest observer proposals (75% of PRIMA’s observing time).
