Query: Far infrared observations of the southern Galactic star forming complex
  around IRAS 09002-4732   The Galactic star forming region in the southern sky, associated with IRAS
09002-4732 has been mapped simultaneously in two far infrared bands (148 & 209
um), with ~ 1' angular resolution. Fifteen sources including IRAS 08583-4719,
08589-4714, 09002-4732 and 09014-4736 have been detected, some of which are
well resolved. Taking advantage of similar beams in the two bands, a reliable
dust temperature [T(148/209)] map has been obtained, which detects colder dust
(< 30 K) in this region. The HIRES processed IRAS maps at 12, 25, 60 & 100 um
have also been used for comparison. The optical depth maps at 200 um & 100 um,
generated from these FIR data quantify the spatial distribution of the dust.
The diffuse emission from this entire region has been found to be 35 % of the
total FIR luminosity. The slope of the IMF in the mass range 4-16 M_sun has
been estimated to be -1.25^+0.75_-0.65 for this star forming complex.
  Radiative transfer models have been explored to fit available observations of
the 4 IRAS sources and extract various physical parameters for corresponding
dust-gas clouds. Whereas a constant radial density distribution is favoured in
IRAS 08583-4719, 08589-4714 & 09002-4732, the r^-1 law is inferred for IRAS
09014-4736. The dust composition is found to be similar (Silicate dominated) in
all the 4 sources. The luminosity per unit mass is found to be in the narrow
range of 44-81 L_sun/M_sun for these star forming regions.
