The Magnificent Seven have all been discovered by their exceptional softX-ray spectra and high ratios of X-ray to optical flux. They all are consideredto be nearby sources. Searching for similar neutron stars with largerdistances, one expects larger interstellar absorption resulting in harder X-raycounterparts. Current interstellar absorption treatment depends on chosenabundances and scattering cross-sections of the elements as well as on the 3Ddistribution of the interstellar medium. After a discussion of these factors weuse the comprehensive 3D measurements of the Local Bubble by Lallement et al.2003 to construct two simple models of the 3D distribution of the hydrogencolumn density. We test these models by using a set of soft X-ray sources withknown distances. Finally, we discuss possible applications for distanceestimations and population synthesis studies.Comment: 8 pages, 7 figures; to appear in Astrophysics and Space Science, in  the proceedings of "Isolated Neutron Stars: from the Interior to the  Surface", edited by D.
