NaI and CaII interstellar absorption

DOI

We present new high resolution (R>50000) absorption measurements of the NaI doublet (5889-5895{AA}) along 482 nearby sight-lines, in addition to 807 new measurements of the CaII K (3933{AA}) absorption line. We have combined these new data with previously reported measurements to produce a catalog of absorptions towards a total of 1857 early-type stars located within 800pc of the Sun. Using these data we have determined the approximate 3-dimensional spatial distribution of neutral and partly ionized interstellar gas density within a distance-cube of 300pc from the Sun.
