Description:
We present the results obtained in the X-ray and infrared study in
the star-forming region NGC2023. The X-ray observation (ID=0112640201)
was performed as a single 30ks exposure on 2002. Afer our processing,
the useful exposure time was reduced around to 15ks. Spitzer
photometry (AORKEY 8773120 and 8773632) we used MOPEX to create the
mosaic image and DAOPHOT package to derived the fluxes. Optical
photometry (V and I magnitude) was obtained from DENIS and
Mid-Infrared from 2MASS and WISE. We used Robitaille et al.
(2007ApJS..169..328R 2007ApJS..169..328R) to SED fitting and derived stellar parameters.
