Newly identified stars in the Jurassic structure analyzed in this work. Differences in atmospheric parameters and elemental abundances produced by two runs adopting different effective temperatures (T_eff) and surface gravities (log g): photometric versus uncalibrated ASPCAP values. The symbols are color-coded by the differences between the photometric and uncalibrated ASPCAP temperatures. The average and ± errors (the standard deviation around the mean of the differences) are listed in the title of each panel.
