  From the entire dataset of comets observed by NEOWISE, we have analyzed 11
different Halley-Type Comets (HTCs) for dust production rates, CO+CO2
production rates, and nucleus sizes. Incorporating HTCs from previous studies
and multiple comet visits we have a total of 21 stacked visits, 13 of which are
active and 8 for which we calculated upper limits of production. We determined
the nucleus sizes of 27P, P/2006 HR30, P/2012 NJ, and C/2016 S1. Furthermore,
we analyzed the relationships between dust production and heliocentric
distance, and gas production and heliocentric distance. We concluded that for
this population of HTCs, ranging in heliocentric distance from 1.21 AU to 2.66
AU, there was no significant correlation between dust production and
heliocentric distance, nor gas production and heliocentric distance.
