I have added additional cores to the analysis, because why not? Below are the regions selected for each core region. Regions were chosen to include a diffuse part and separate from other structures. The identified regions are from Lombardi et al. (2010), described in this post. I included additional regions besides the ones listed by Lombardi 2010, by labeling the new region as a second part of the nearest region.

Below are the results for each cloud. The contours represent binned counts in logarithmic points. Cores contain a few hundred points each.

Taurus:

### Distance from galactic plane

Next result is furthering the result from the latter half of this post, which discusses the predicted $T_{\rm CNM}$ from the K+09 model vs. galactic latitude. Here we take it a step further and consider the core region distance from the galactic plane. To calculate the distance from the galactic plane take the following geometry

where $z_\odot$ is the scale height of the sun wrt the galactic plane, $z_c$ is the scale height of the cloud wrt the galactic plane, $d_c$ is the cloud distance from the galactic plane along the LOS from the sun, $d_\odot$ is the distance between the sun and the galactic plane along the LOS, and $D$ is the distance to the cloud. Given

we can solve for $z_c$ as

This gives us the following trend between $T_{\rm CNM}$ and distance from the galactic plane (not much of a trend)
