Results of long-slit spectral observations of Arp263

Long-slit spectral data of Arp263 along 3 position angles (PA=256, 289, 318) taken with BTA SAO RAS. The folders names correspond to the position angle of the spectral cut. Each folder contains reduced spectra (sum_abs.fts), error files (err_sum_abs.fts) and the map which corresponds to the slit situated vertically in the image in the pixel given as 'SLITPOS' in the header of the firs-file.
