NIKA2 bandpasses of the 3 arrays are described in Section 2.5 and Figure 1 of [[https://ui.adsabs.harvard.edu/abs/2020A%26A...637A..71P/abstract|Perotto et al. (2020)]].

For convenience, we provide here a fits file [[attachment:Transmission_2017_Jan_NIKA2_v1.fits]] (priv. com. Juan-Macias Perez 12-Jun-2020) '''FOR A SLIGHTLY DIFFERENT VERSION OF THE BANDPASSES'''. The 2mm bandpass is valid since September 2016 (Run N2R5).
For convenience, we provide here the three bandpasses: [[attachment:nika2-2mm-band.dat]], [[attachment:nika2-1mm-1.dat]], [[attachment:nika2-1mm-2.dat]]. These bandpasses have already been corrected for the Rayleigh-Jeans source emission. They are shown in the figure below and also in Figure 1 of [[https://ui.adsabs.harvard.edu/abs/2020A%26A...637A..71P/abstract|Perotto et al. (2020)]].

Information for Observers on NIKA2 Bandpasses

Bandpasses of the NIKA2 Arrays

For convenience, we provide here the three bandpasses: nika2-2mm-band.dat, nika2-1mm-1.dat, nika2-1mm-2.dat. These bandpasses have already been corrected for the Rayleigh-Jeans source emission. They are shown in the figure below and also in Figure 1 of Perotto et al. (2020).

Atmospheric transmission curves

The ATM model of J.Pardo & P.Cernicharo was used to calculate the atmospheric transmission at Pico Veleta for three different amounts of precipitable water vapour: 2, 4, 7mm: atmos2mm.dat, atmos4mm.dat, atmos7mm.dat.

The spectral bands as measured in Néel (note that the two 1.15mm arrays are pretty similar but there is a detectable difference):
