== Information for Observers on NIKA2 Bandpasses ==
=== Bandpasses of the NIKA2 Arrays ===

For convenience, we provide here the three bandpasses: [[attachment:nika2-2mm-band.dat]], [[attachment:nika2-1mm-band-1.dat]], [[attachment:nika2-1mm-band-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)]]. 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 for three different amounts of precipitable water vapour: 2, 4, 7mm: [[attachment:atmos2mm.dat]], [[attachment:atmos4mm.dat]], [[attachment:atmos7mm.dat]]. See also the figure below.

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-band-1.dat, nika2-1mm-band-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). 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 for three different amounts of precipitable water vapour: 2, 4, 7mm: atmos2mm.dat, atmos4mm.dat, atmos7mm.dat. See also the figure below.
