Notes. The distance relative to the solar system and the Galactocentric radius are denoted d and RGC respectively. The positions given are the pointing centers of the MIRI/MRS observations, which are generally offset from the protostar positions and centered on the blue outflow lobes.(1) Total integration time of all three gratings per pointing.
