== Information for Observers on NIKA2 Bandpasses ==

=== Bandpasses of the NIKA2 Arrays ===

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).

=== 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]].

Information for Observers on NIKA2 Bandpasses

Bandpasses of the NIKA2 Arrays

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).

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.
