Comparison of emission brightness for HCO+ and 12CO. Left: channel-channel comparison for the six new anticenter sources with WCO > 1 K-km s−1. Right: integrated HCO+ emission plotted against WCO with new data from this work overlaid on earlier observations taken around and well removed from continuum background sources. This was previously shown as Figure 8 in Liszt (2020).
