scientific abstract this proposal sets out a plan for observations of the driving sources for herbig-haro (hh) flows, using both isophot-p and isophot-c to obtain maximum wavelength coverage. with the help of sub-mm observations, vital information on the evolution of disks around low-mass objects and their role in the mass loss phenomena can be derived. observation summary it is intended to perform broad band photometry on the energy sources with a variety of filters, but ensuring that there is always enough sky to allow background subtraction. in order to achieve 5% photometry, the minimum integration time per filter should be 32sec. this has, therefore, been selected as the standard integration time. with the pht-c detector a one-dimensional scans will be made at 200um, adding new science, possibly never again achievable. pht-p aot - pht03 peak-up required rectangular chopping - 60 throw filter aperture integration on source 10 23 32 12.8 23 32 16 23 32 20 23 32 25 23 32 pht-c aot - pht32 1x4 scan filter integration c200 14s per raster position (2s per chop step)

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
