| 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). The 2mm bandpass is valid since September 2016 (Run N2R5). | For convenience, we provide one ASCII file with the three NIKA2 bandpasses and three atmospheric transmission curves for 2mm, 4mm, and 7mm of precipitable water vapour: [[attachment:nika2-bandpasses-atm.dat]]. The instrumental 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)]]. These bandpasses were measured in the laboratory in Grenoble. |

Bandpasses of the NIKA2 Arrays
For convenience, we provide one ASCII file with the three NIKA2 bandpasses and three atmospheric transmission curves for 2mm, 4mm, and 7mm of precipitable water vapour: nika2-bandpasses-atm.dat. The instrumental 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). These bandpasses were measured in the laboratory in Grenoble.
Atmospheric transmission curves
The ATM model of J.Pardo & P.Cernicharo was used to calculate the atmospheric transmission at Pico Veleta. See also the figure below.
