A compilation of interstellar column densities
Listed in IVOA Registry (Virtual Observatory)
We have collated absorption line data toward 3008 stars in order to create a unified database of interstellar column densities.
Description
These data have been taken from a number of different published sources and include many different species and ionizations. The preliminary results from our analysis show a tight relation [N(H)/E(B-V)=6.12x10^21^] between N(H) and E(B-V).
Similar plots have been obtained with many different species, and their correlations along with the correlation coefficients are presented.
