General Description

The general goal of these VISIR observations is to make a census of the
 massive protostellar population wihin 5 molecular cores. We expect to image point
 sources at the target positions as well as possibly extended emission around them.
 The fluxes should vary between 50 mJy and 5 Jy in the PAH1 band and between 0.5
 Jy and 10 Jy in the Q2 band. 

There are 5 sources to be observed in 2 bands (PAH1 and Q2).

Three sources are relatively "strong" in mid-IR and should be clearly detected in
 the acquisation
observation: these sources are G318.95-0.20, G335.58-0.29, G31.41+0.31. OBs have
 prepared for each
band (PAH1 and Q2) for these sources.

Two sources will be faint in the acquisation observation: G30.72-0.08 and G25.83-0.17.
 OBs for these sources contain both PAH1 and Q2 blocks.

Charts are provided for each source. They show a large scale mid-IR image of the
 region and a close-up NIR iamge of the target 1-2' environment. The target position
 is marked with a cross and indified as "target" on the image. 

In the case of G318.95-0.20, G335.58-0.29, G31.41+0.31, we expect the mid-IR source
 to coincide with the NIR source associated with the target in the close-up image.
