Abstract:
We present here the stability results of the high frequency heterodyne instrument (HIFI), to be flown on the Herschel space observatory. The measurements were taken as part of the instrument level tests (ILT) in the spring of 2007. Herschel is ESA's fourth cornerstone mission in the Horizon 2000+ program, and aims at observations in the Far-InfraRed and sub-millimeter wavelength region. HIFI itself is one of three instruments onboard Herschel. The other two being PACS, the photodetector array camera and spectrometer, and SPIRE, the spectral and photometric imaging receiver. The detailed instrument stability measurements were conducted to establish the functionality, and observational readiness of the instrument.
