The HI line magnitude m21 has been corrected for self-absorption effect following Heidmann et al (1972) , with parameter kappa=0.031. The inclination needed to compute this correction is given as parameter incl . If inclination is higher than 89 deg the maximum correction is limited to -0.82 mag. Corrected flux at other wavelengths are given in the parameters: bt , it . The measured HI flux is m21 .
