SUMMARY:Magnetic field components analysis of the SCUPOL 850 microns polari
 zation data catalog
DESCRIPTION:Magnetic field components analysis of the SCUPOL 850 microns po
 larization data catalog\nDr. Frederick Poidevin\n\nI will present an exten
 sive analysis of the 850 microns (353 GHz)  polarization maps of the SCUBA
  Polarimeter Legacy (SCUPOL) Catalogue  produced by Matthews et al., focus
 ing on the molecular clouds and  star-forming regions. The first half of t
 he presentation will concern  the several methods used in order to analyze
  and characterize the  observed polarization maps and a statistical analys
 is of the results  will be presented. The second half of the talk will foc
 us on a method  used for describing the turbulent regimes of the four well
  sampled  regions, S106, OMC-2/3, W49, and DR21, based on comparisons with
   three-dimensional magnetohydrodynamics (MHD) numerical simulations  scal
 ed to the observed polarization maps. It will be shown how this  method ca
 n be used for constraining the values of the inclination angle  of the mea
 n magnetic field with respect to the line of sight.  Consistency of the re
 sults obtained from the comparison of the  information extracted from the 
 analysis of the observed and simulated  maps with results obtained from in
 dependent observation data analysis by  other authors will be discussed. C
 onclusions regarding how simple,  ideal, isothermal, and non-self-gravitat
 ing MHD simulations may be  sufficient in order to describe the large-scal
 e observed physical  properties of some molecular cloud envelopes will be 
 given.
