Distances of GO45.1-03.4. The corner plots of the MCMC samples of five modeled parameters and their uncertainties are displayed on the left. The right panel displays the distance result. The vertical black lines indicate the estimated distance (D), and the shadow areas depict the 16th and 84th percentile values of the cloud distance. The broken horizontal dashed purple line is the color variation of the on-cloud stars after the baseline was subtracted.
