Abstract:
We have observed the cosmic microwave background (CMB) temperature
fluctuations in eight fields covering three separated areas of sky
with the Very Small Array at 34GHz. A total area of 101 square
degrees has been imaged, with sensitivity on angular scales of
3.6°-0.4° (equivalent to angular multipoles l=150-900).

Note (1): In Simbad, sources are designated as [TCC2003b] JHHMMSS.s+DDMMSS
Note (2): The apparent flux is the flux of each source at 34GHz as observed by
the VSA (i.e. including the effect of the VSA primary beam).
this flux represents the actual flux subtracted from each map.
