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).
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.
