The L1551 IRS 5 outflow was detected at 60 and 100 microns
by the IRAS satellite. This emission has been attributed to
dust grains transiently heated by UV photons from shocks with the
supersonic flow. A comparison of the mechanical luminosity of this outflow,
derived from CO data, and estimates of its infrared luminosity,
shows that the outflow should be momentum driven. There are, however,
several problems in interpreting CO data, such as projection effects,
which make a statistical approach, to determining whether outflows are
momentum or energy driven, more appropriate.  The purpose of this proposal
then is to find, and map, further examples of infrared emission from
bipolar molecular outflows and to determine their spectral energy
distributions. This will enable us to test, in general, whether
outflows are energy or momentum conserving, and to measure how much
energy is fed back into the molecular cloud for turbulent support.

The targeted outflows will be raster mapped using AOT PHT32 and the
PHT-C100 detector over the complete length of the outflows as
determined from CO maps. The filters required are C_60 and C_90. Follow-up
observations with the PHT-C200 detectors will be performed on the basis of
these maps. The oversampling factor will be 2 and the maps will cover areas
of 8'x4' (B335), 6'x4' (NGC2071), 4'x4' (HH7-11), 3'x6' (L1448), 4'x4'(L483). 
The typical S/N will be approximately 10 assuming a flux of one tenth of that
of the L1551 outflow.
