PESSTO settings for SOFI spectroscopy.

Notes. The order blocking filters used are 0.925 μm (GBF) and 1.424 μm (GRF) “cut-on” filters. A slit projects to 3.4 pixels FWHM, measured from arc lines and the resolution R is given at the midpoint of the spectral ranges, as is the velocity resolution. The column headed Arclines indicates the number of lines used. The rms is the typical residual for the wavelength calibration solution.
