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.
