ISOCAM data processing

Aussel, H.; Abergel, A.; Pantin, E. +6 more

The ISOCAM infrared camera is one of the four instruments on board the ISO (Infrared Space Observatory) spacecraft which was launched successfully on 1995 November 17. It operates in the 2.5 - 18 mu m range, and was developed by the ISOCAM consortium lead by the French Service d'Astrophysique of CEA Saclay. This paper presents different algorithms…

Faint source detection in ISOCAM images

Aussel, H.; Elbaz, D.; Cesarsky, C. +2 more

We present a tool adapted to the detection of faint mid-infrared sources within ISOCAM mosaics. This tool is based on a wavelet analysis which allows us to discriminate sources from cosmic ray impacts at the very limit of the instrument, four orders of magnitudes below IRAS. It is called PRETI for Pattern REcognition Technique for ISOCAM data, bec…

Young massive stars in the ISOGAL survey. I. VLA observations of the ISOGAL l=+45 field

Felli, M.; Testi, L.; Taylor, G. B.

We present VLA radio continuum observations at 3.6 and 6 cm of a ~ 0.65 sq. deg. field in the galactic plane at l=+45(deg) . These observations are meant to be used in a comparison with ISO observations at 7 and 15 mu m of the same region. In this paper we compare the radio results with other radio surveys and with the IRAS-PSC. At 3.6 and/or 6 cm…

Observations of GRBs with the Infrared Space Observatory

Altieri, B.; Piro, L.; Palazzi, E. +17 more

We present results from the Target of Opportunity (TOO) program to observe GRB locations with the CAM and PHOT instruments aboard the Infrared Space Observatory (ISO). Four BeppoSAX/ GRB error circles were observed by ISO on timescales ranging from days to months after the GRB events. These observations represent the first prompt GRB counterpart s…
