Abstract

Synthetic colours for main sequence stars, computed as described in Section 4 from model atmospheres, are here tabulated in full for three representative reddening laws (RV = 2.5, 3.1 and 3.8) and a range of reddenings (A0 = 0, 2, 4, 6, 8, 10). The form of the reddening laws used is due to Fitzpatrick & Massa (2007ApJ...663..320F, Cat. J/ApJ/663/320). When using the blue-filter tables, it should be borne in mind that beyond g-r~3, the red leak in the u filter signif- icantly alters u-g. In this domain we expect the synthetic colours to progressively become less reliable as they increas- ingly depend on hard-to-measure very low levels of red trans- mission. Objects that appear to have these extreme, peculiar colours are likely to be reddened red giants or supergiants, since reddened K-M main sequence stars are too faint to be detected in VPHAS+ exposures. Beyond g-r~3.5 these table entries are italicised. Two further tables of synthetic colours are included for K-M giants that have been computed using P98 library spectra. Data are provided for the RV=3.1 mean Galactic law only, for the limited purposes of (a) giving an impres- sion of how these luminous red objects may contaminate (u-g, g-r) diagrams at redder (g-r) through u red leak (b) enabling comparisons with the M-giant spur commonly seen in (r-Hα, r-i) colour-colour diagrams.
