Notes. Columns are: logarithm of the pulsation period (P), E(BV) from Storm et al. (2011a) used for the IRSB analysis, E(BV) tabulated by Laney & Caldwell (2007). The table also details the spectroscopic data available for these stars (F: FEROS, H: HARPS, N: HARPS-N, S: STELLA, U:UVES). The upper panel lists Galactic Cepheids, the lower panel Magellanic Cepheids. SMC stars (identified in italics) have not been used for training or testing, but only for assessing that the current relations do not hold anymore at the metallicities of SMC Cepheids (see Sect. 5.1).

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.
