HCN $J$=4-3, HNC $J$=1-0, $mathrm{H^{13}CN}$ $J$=1-0, and $mathrm{HC_3N}$ $J$=10-9 Maps of Galactic Center Region I: Spatially-Resolved Measurements of Physical Conditions and Chemical Composition

This {it supplement} paper presents the maps of HCN $J$=4-3, HNC $J$=1-0, $mathrm{H^{13}CN}$ $J$=1-0, and HC$_3$N $J$=10-9 for the Galactic central molecular zone (CMZ), which have been obtained using the Atacama Submillimeter Telescope Experiment and Nobeyama Radio Observatory 45-m telescope. Three-dimensional maps (2-D in space and 1-D in velocity) of the gas kinetic temperature ($T_mathrm{kin}$), hydrogen volume density ($n_mathrm{H_2}$), and fractional abundances of eight molecules (HCN, HNC, $mathrm{HC_3N}$, HCO$^+$, $mathrm{H_2CO}$, SiO, CS, and $mathrm{N_2H^+}$) have been constructed from our and archival data. We have developed a method with hierarchical Bayesian inference for this analysis, which has successfully suppressed the artificial correlations among the parameters created by systematic errors due to the deficiency in the simple one-zone excitation analysis and the calibration uncertainty. The typical values of $T_mathrm{kin}$ and $n_mathrm{H_2}$ are $10^{1.8} $K and $10^{4.2} mathrm{cm}^{-3}$, respectively, and the presence of an additional cold/low-density component is also indicated. The distribution of high-temperature regions is poorly correlated with known active star-forming regions, while a few of them coincide with shocked clouds. Principal component analysis has identified two distinct groups in the eight analyzed molecules: one group with large PC1 and PC2 scores and the other with a large $T_mathrm{kin}$ dependence, which could be explained using two regimes of shock chemistry with fast ($gtrsim 20 mathrm{km,s}^{-1}$) and slow ($lesssim 20 mathrm{km,s}^{-1}$) velocity shocks, respectively. This supports the idea that the mechanical sputtering of dust grains and the mechanical heating play primary roles in the chemical and thermal processes in CMZ clouds.
