Figure 2. The FIR SEDs from the galaxies in our
sample. The color
corrected flux densities at 60, 100 and 170 µm are plotted
together with their associated error bars. One galaxy, VCC 1110 has
additional measurements at 70 and 120 µm. The two modified
black-body functions which best fitted the data points are plotted
with dashed-lines. The temperature of the warm component is
constrained to be 47 K. The fitted temperature of the cold component
is marked near each fit. The sum of the two fitting functions is
plotted as the solid line. Some galaxies don't show evidence for two
dust components and their SEDs are fitted with single component
modified black-body functions, plotted as solid lines.
