1999A&AS..137..495S An H{alpha} catalogue of galaxies in Hickson compact groups. I. The sample. SEVERGNINI P., GARILLI B., SARACCO P., CHINCARINI G. Received January 8; accepted April 21, 1999 Abstract: We present H{alpha} photometry for a sample of 95 galaxies in Hickson Compact Groups obtained from observations of 31 groups. The Catalogue lists isophotal and adaptive aperture (Kron aperture) flux measurements for about 75% of the accordant galaxies inside the observed HCGs, 22 out of which are upper limits. Non standard data reduction procedures have been used to obtain the continuum subtracted H{alpha} images for each HCG of the target sample. Flux calibration has also been performed in order to obtain H{alpha} luminosities for the whole sample. Both the data reduction and calibration procedures are carefully described in this paper. The new data listed in this Catalogue are of great importance in understanding the star formation rate inside HCG galaxies and in giving new insights on its dependence on galaxy interactions. Key words: galaxies: clusters: general - galaxies: evolution - galaxies: interaction
