CLASS 40 GHz 2016 - 2022 Observations (DR1)


Download Links:

The 40 GHz bandpass represents an adopted aggregate over different instrument configurations occurring during the 2016 - 2022 40 GHz survey. The bandpass file is in ASCII format with two columns: frequency in GHz and normalized response.

Color correction information is provided in Eimer et al. (2023).
