The first method infers $\Sigma_SFR$ from the observations of the dust thermal emission from interstellar dust grains in far infrared wavelengths registered in the Herschel Infrared Galactic Plane Survey (Hi-GAL), as presented in Elia et al. (2022). The second method obtains $\Sigma_SFR$ by modeling the current population of O-, B-, and A-type stars in a 6 kpc $\times$ 6 kpc area around the Sun, as presented in Zari et al. (2023). We found an agreement between the two methods within a factor of two for the mean SFRs and the SFR surface density profiles. Given the broad differences between the observational techniques and the independent assumptions in the methods to compute the SFRs, this agreement constitutes a significant advance in our understanding of the star formation of our Galaxy and implies that the local SFR has been roughly constant over the past 10 Myr.
