Flux calibration of the Herschel -SPIRE photometer
We describe the procedure used to flux calibrate the three-band submillimetre photometer in the Spectral and Photometric Imaging Receiver instrument on the Herschel Space Observatory. This includes the equations describing the calibration scheme, a justification for using Neptune as the primary calibration source, a description of the observations and data processing procedures used to derive f...
متن کاملSPS: a software simulator for the Herschel-SPIRE photometer
Aims. Instrument simulators are becoming ever more useful for planning and analysing large astronomy survey data. In this paper we present a simulator for the Herschel-SPIRE photometer. We describe the models it uses and the form of the input and output data. Methods. The SPIRE photometer simulator is a software package which uses theoretical models, along with flight model test data, to perfor...
متن کاملIn-flight calibration of the Herschel-SPIRE instrument*
SPIRE, the Spectral and Photometric Imaging REceiver, is the Herschel Space Observatory’s submillimetre camera and spectrometer. It contains a three-band imaging photometer operating at 250, 350 and 500 μm, and an imaging Fourier-transform spectrometer (FTS) covering 194−671 μm (447−1550 GHz). In this paper we describe the initial approach taken to the absolute calibration of the SPIRE instrume...
متن کاملPhysics based calibration of the Herschel/SPIRE bolometers
The bolometers (and readout circuitry) in the SPIRE instrument on the Herschel Space Observatory are among the best understood and well characterised of any sub-mm astronomy instrument to date. SPIRE contains five arrays of NTD germanium spiderweb bolometers with up to 139 pixels per array. Their behaviour has been shown to be extremely stable as seen by repeated measurements in the years betwe...
متن کاملThe Herschel-SPIRE submillimetre spectrum of Mars*
We have obtained the first continuous disk averaged spectrum of Mars from 450 to 1550 Ghz using the Herschel-SPIRE Fourier-transform spectrometer. The spectrum was obtained at a constant resolution of 1.4 GHz across the whole band. The flux from the planet is such that the instrument was operated in “bright source” mode to prevent saturation of the detectors. This was the first successful use o...
