We present the HI distribution of galaxies from the Continuum Halos in NearbyGalaxies - an EVLA Survey (CHANG-ES). Though the observational mode was notoptimized for detecting HI, we successfully produce HI cubes for 19 galaxies.The moment-0 maps from this work are available on CHANG-ES data releasewebsite, i.e., https://www.queensu.ca/changes. Our sample is dominated bystar-forming, HI-rich galaxies at distances from 6.27 to 34.1 Mpc. HIinterferometric images on two of these galaxies (NGC 5792 and UGC 10288) arepresented here for the first time, while 12 of our remaining sample galaxiesnow have better HI spatial resolutions and/or sensitivities of intensity mapsthan those in existing publications. We characterize the average scale heightsof the HI distributions for a subset of most inclined galaxies (inclination >80 deg), and compare them to the radio continuum intensity scale heights, whichhave been derived in a similar way. The two types of scale heights are wellcorrelated, with similar dependence on disk radial extension and star formationrate surface density but different dependence on mass surface density. Thisresult indicates that the vertical distribution of the two components may begoverned by similar fundamental physics but with subtle differences.
