We report the strategy for observing the Sunyaev-Zeldovich effect towards the Coma cluster of galaxies with the MITO telescope. The instrument has a 17 arcminutes FWHM field of View and uses a 3-field square wave mechanical modulation with a beamthrow of 41 arcminutes. The channels centered at 2.1, 1.4, 1.1 and 0.85 mm allow for matching the Sunyaev-Zeldovich effect spectral range and monitoring atmospheric fluctuations for spectral decorrelation. in this paper we describe both the analysis procedure and the preliminary results of our observations. We also make a first comparison with the available X-ray data.

Abstract
We report the strategy for observing the Sunyaev-Zeldovich effect towards the Coma cluster of galaxies with the MITO telescope. The instrument has a 17 arcminutes FWHM field of View and uses a 3-field square wave mechanical modulation with a beamthrow of 41 arcminutes. The channels centered at 2.1, 1.4, 1.1 and 0.85 mm allow for matching the Sunyaev-Zeldovich effect spectral range and monitoring atmospheric fluctuations for spectral decorrelation. in this paper we describe both the analysis procedure and the preliminary results of our observations. We also make a first comparison with the available X-ray data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
