Description:
    HII region catalogue of the barred galaxy NGC 7479. The catalogue
    contains the position, mean radius and the calibrated H-alpha
    luminosity of each HII region. The HII region catalogue has been
    composed using a new semi-automated technique applied to a high
    quality continuum-subtracted H-alpha image of the galaxy obtained from
    observations through the TAURUS camera in imaging mode with the 4.2m
    WHT on La Palma. An EEV CCD 7 detector was used with a projected pixel
    size of 0.279". More details about the reduction and the catalogue
    production procedures are given in the paper.
