Description

The determination of the supernova (Sn) rate is based not only on the number of detected events but also on the properties of the parent galaxy population. This is the first paper of a series aimed at obtaining new, refined, Sn rates from a set of five Sn surveys by making use of a joint analysis of near-infrared (Nir) data. We describe the properties of the 3838 galaxies that were monitored for S Ne events, including newly determined morphologies and their Denies and Poses-II/Ust I, 2MASS and DENIS J and KS and 2MASS H magnitudes. We have compared 2MASS, DENIS and POSS-II/UKST IJK magnitudes in order to find possible systematic photometric shifts in the measurements. The DENIS and POSS-II/UKST I band magnitudes show large discrepancies (mean absolute difference of 0.4 mag.), mostly due to different spectral responses of the two instruments, with an important contribution (0.33 mag rms) from the large uncertainties in the photometric calibration of the POSS-II and UKST photo-graphic plates. In the other wavebands, the limiting near infrared magnitude, morphology and inclination of the galaxies are the most influential factors which affect the determination of photometry of the galaxies. Nevertheless, no significant systematic differences have been found between of any pair of NIR magnitude measurements, except for few percent of galaxies showing large discrepancies. This allows to combine DENIS and 2MASS data for the J and KS filters
