EXoPLORE — CARMENES NIR reference night files for HD 189733 b

Per-pixel signal-to-noise ratio (snr_0.fits, shape 45×28×4080), per-pixel uncertainty (sig_0.fits, same shape), and per-order normalised observed spectra (observations_night_0_order_0.fits … observations_night_0_order_27.fits) for one CARMENES NIR transit observation of HD 189733 b on the night of 7–8 September 2017. Used by the EXoPLORE simulator (https://github.com/asanchezlopezIAA/EXoPLORE) as reference-night input for tutorials. The 45 spectra cover 28 echelle orders (0.96–1.71 µm) at R ≈ 80,400. These data were first published in Alonso-Floriano et al. (2019, A&A, 621, A74) and subsequently used in Sánchez-López et al. (2019, A&A, 630, A53) and Blain, Sánchez-López & Mollière (2024, AJ, 167, 179). Based on data from the CAHA Archive at CAB (INTA-CSIC). The CAHA Archive is part of the Spanish Virtual Observatory project funded by MCIN/AEI/10.13039/501100011033 through grant PID2023-146210NB-I00.
