We are requesting official STAR preliminary status for the results on these three figures. The first figure (the transverse mass spectra) was approved in October 2017. The STAR results in figures three and four are identical.

Documentation that helps support the figures can be found here : http://nuclear.ucdavis.edu/~kinghorn/protected/QM2018/Al+Au_4_9GeV_PionMinus_SpectraAnddNdy_2018_forQM.pdf
