RA-Dec map of the stars that are likely members of the Perseus complex young clusters and associations (gray dots), based on their distances and proper motions, within a projected area of about 10 degrees on sky (left). Black dots mark the 84 stars that were spectroscopically observed within the TNG-SPA Large Program, and red circles mark the 27 RSGs we studied. For reference, we also plot the main clusters in the region in blue. Gaia eDR3 CMD for the same stars as in the left panel (right).
