VizieR Online Data Catalog: Deuterated methanol in comet 67P/C-G (Drozdovskaya+, 2021)
Abstract
The ROSINA Double Focusing Mass Spectrometer (DFMS) has a high-mass resolution of m/Δm=3000 for a m/z (mass-to-charge ratio) of 28 at 1 per cent of the peak height (Balsiger et al. 2007SSRv..128..745B). Its main detector, the MCP/LEDA, is a position-sensitive imaging detector that is a stack of two micro-channel plates (MCPs) arranged in Chevron configuration, followed by two independent rows (Rows A and B) of 512 anodes on a linear electron detector array (LEDA). For the measurement mode discussed in this paper, spectra around each integer mass are obtained consecutively every 30s (10s for adjusting voltages and 20s of integration time).
Quantities of methanol and its isotopologues from star-forming regions to comets used to construct Figs 2-4 and B1-B3 are tabulated in Table D2 alongside their respective references. The full descriptions of the probed locations in each source can be found in the corresponding publications, as well as the beam sizes of the observations, and assumptions about the source sizes. The isotopic ratios used in the various publications are given in Table D1. (2 data files).- Publication:
