A typical droplet in L1688 (L1688-4; see Paper I): Maps of total column density (\(N_{\text{H}_2}\)), dust temperature (\(T_\text{dust}\)), peak ammonia brightness in units of main-beam temperature (\(T_\text{peak}\)), velocity dispersion (\(\sigma_{\text{NH}_3}\)), observed velocity centroid (\(V_\text{LSR}\)), and predicted velocity centroid based on the fitted model of a linear model of a linear velocity gradient (\(V_\text{LSR,pred}\); see ยง\ref{283729}). The white contour shows the droplet boundary (see Paper I), where the velocity gradient fitting is carried out. The yellow star shows the position of a c2d YSO source (Dunham et al., 2015). The circle on the bottom left shows the beam FWHM of GAS observations. (xx change to a plot showing the velocity gradient and the fits only.)
