NOT spectrum of 2MASX J02301709+2836050; 2022-07-16

Ascii file giving the optical spectrum of 2MASX J02301709+2836050, host galaxy of the transient Swift J023017.0+283603. This is in plain text with 3 columns, separated by spaces. These columns are: * Wavelength in Angstroms * Flux density erg /s cm^2 /Angstromg AA-1. * 1-sigma error on the flux density. The spectrum was obtained on 2022 July 16, and comprises a 2.4 ks exposure using the Alhambra Faint Object Spectrograph and Camera mounted on the 2.56-m Nordic Optical Telescope located at La Palma, Spain. A 1" slit was used, with Grism #19. The airmass during the observation was of the order of 1.46. The spectrum is in the observer's frame andhas been dereddened to correct for the Galactic reddening of E(B-V) = 0.0866. Note: This spectrum was not used in the final submitted paper, but was used in early analysis,
