PRobing InterStellar Molecules with Absorption line Studies (PRISMAS) Overview
PRISMAS Overview PRISMAS Data Access PRISMAS Data Table


High-resolution Herschel HIFI spectroscopy of ~25 molecules (hydrides containing the elements H, D, C, N, O, F and Cl) detected in absorption against the background emission of 10 sources (two directions towards Sgr A, W28A, W31C, W33A, G34.3+01, W49N, W51, DR21(OH) and W3-IRS5) observed as part of the PRISMAS key programme (KPGT_mgerin_1). For each observation, the delivery comprises the calibrated reduced HIFI data corrected for instrumental artifacts in CLASS-readable FITS table format and in generic FITS table format, together with quick-look plots marking the main transitions detected, and various HIPE/CLASS scripts useful to reproduce or to independently perform the data reduction.
