Notes: Targets are identified by HD number or alternative catalogue designations for those not in the HD catalogue. The instrument used is denoted by C for CRIRES (no adaptive optics), CAO for CRIRES using adaptive optics, X for data from Minniti et al. (2020), XA for archival X-shooter data, and XL for the X-shooter low water vapour sample. Spectral types, Gaiactic coordinates, and apparent magnitudes in the B, V, and H bands are taken from SIMBAD. CC indicates a classical Cepheid and T2C a type 2 Cepheid; the intrinsic colours of these stars vary over the pulsation period. Cepheid names are from Minniti et al. (2020), where B refers to a Bulge Cepheid and D to a Disc Cepheid. Intrinsic (B - V)0 colours for the spectral type are taken from Fitzgerald (1970) and Wegner (1994); where the values differed, we took an average. Reddening E(B-V) was estimated by comparing the observed (B - V) colours to the intrinsic colours, except for the entries taken from the literature shown in the footnote and towards the Cepheids, as explained in the text. NObs indicates the number of observations in each of the five wavelength regions observed using CRIRES, with central wavelengths (a) 1318.1 nm, (b) 1527.9 nm, (c) 1568.8 nm, (d) 1574.4 nm, and (e) 1624.2 nm. All wavelengths were observed in a single setting for X-shooter. There are no SIMBAD data for 145501 B nor 160065 B that were detected using CRIRES.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
