NIKA2 Bandpasses
Information for Observers
NIKA2 bandpasses of the 3 arrays are described in Section 2.5 and Figure 1 of Perotto et al. (2020). For convenience, we provide here a fits file Transmission_2017_Jan_NIKA2_v1.fits (priv. com. Juan-Macias Perez 12-Jun-2020). The 2mm bandpass is valid since September 2016 (Run N2R5). The following figure shows a resulting plot:
