Herschel/HIFI discovery of interstellar chloronium (H2Cl+) ***
We report the first detection of chloronium, H2Cl, in the interstellar medium, using the HIFI instrument aboard the Herschel Space Observatory. The 212−101 lines of ortho-H35 2 Cl and ortho-H37 2 Cl are detected in absorption towards NGC 6334I, and the 111−000 transition of para-H35 2 Cl is detected in absorption towards NGC 6334I and Sgr B2(S). The H2Cl column densities are compared to those o...
متن کاملThe data processing pipeline for the Herschel SPIRE Fourier Transform Spectrometer
We present the data processing pipeline to generate calibrated data products from the Spectral and Photometric Imaging Receiver (SPIRE) imaging Fourier Transform Spectrometer on the Herschel Space Observatory. The pipeline processes telemetry from SPIRE observations and produces calibrated spectra for all resolution modes. The spectrometer pipeline shares some elements with the SPIRE photometer...
متن کاملHIFISTARS Herschel/HIFI observations of VY Canis Majoris
Aims. The study of the molecular gas in the circumstellar envelopes of evolved stars is normally undertaken by observing lines of CO (and other species) in the millimetre-wave domain. In general, the excitation requirements of the observed lines are low at these wavelengths, and therefore these observations predominantly probe the cold outer envelope while studying the warm inner regions of the...
متن کاملThe effect of sideband ratio on line intensity for Herschel/HIFI
The Heterodyne Instrument for the Far Infrared (HIFI) on board the Herschel Space Observatory is composed of a set of fourteen double sideband mixers. We discuss the general problem of the sideband ratio (SBR) determination and the impact of an imbalanced sideband ratio on the line calibration in double sideband heterodyne receivers. The HIFI SBR is determined from a combination of data taken d...
متن کاملArrayPipe: a flexible processing pipeline for microarray data
A number of microarray analysis software packages exist already; however, none combines the user-friendly features of a web-based interface with potential ability to analyse multiple arrays at once using flexible analysis steps. The ArrayPipe web server (freely available at www.pathogenomics.ca/arraypipe) allows the automated application of complex analyses to microarray data which can range fr...
