Abstract

This survey is derived from the 21cm maps presented by Dickey and Lockman
in the <i>ARAA</i> 28, p215.  The nH is derived assuming optically thin
emission. The nH given should be considered a lower limit when the nH is
greater than several times 10<sup>20</sup>.  Provenance:  provided by S. Snowden from data by Dickey and Lockman. This is a service of NASA HEASARC.
