Deep NIR and optical study on RCW 34 and NGC 2626

An in-depth multi-wavelength has been performed on the two high mass star forming regions RCW 34 and NGC 2626 using NIR photometry from the IRSF, optical photometry from VPHAS+ and optical spectra from SALT. Customary NIR extinction laws were constructed using LINES linear regression method and extinction maps were constructed with the NICEST algorithm. Sources were dereddened and the amount of excess emission for each low-mass member could be tested. Synthesis of all of the data made it possible to construct a "big picture" star forming history for both regions.
