Description

The Probe of Inflation and Cosmic Origins (PICO) is a space mission submitted to the Astro2020 Decadal Review as an inflation probe. In a previous paper (Aurlien et al, 2023), the PICO team demonstrated performance based on simplifying assumptions, in particular, white homogeneous noise. We present updated r forecasts, based on end-to-end simulations, for a realistic noise including inhomogeneous sky coverage and 1/f noise, and increasing foreground model complexity.
