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). The following figure shows a resulting plot:
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.
Previous bandpasses of 2015
The spectral bands as measured in Néel (note that the two 1.15mm arrays are pretty similar but there is a detectable difference):
