... A detailed mathematical derivation of the posterior probability distributions of the hardness ratios and the computational metho ds we use to calculate them are described in Appendix A, and a detailed comparison of the effects of priors is described in Appendix B. 2. ... Given pre-specified values of the parameters, source and background counts were generated and then used to construct 95% classical and posterior intervals of each hardness ratio using the metho ds discussed in this article. ...

... By undertaking a spectral and photometric investi gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...
