NOT spectrum of 2MASX J02301709+2836050; 2022-11-01

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 November 1, 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 #4. The
airmass during the observation was of the order of 1.1.

The spectrum is in the observer's frame andhas been dereddened to correct for the Galactic reddening of  E(B-V) = 0.0866.
