Dereddened optical IPHAS, 2MASS, and GLIMPSE photometry for the six WHT A-type stars with no evidence of 8 μm excesses (blue triangles with error bars denoting the 1σ photometric error of each measurement). For each star, the red solid line corresponds to the photospheric reference of an A3V SED, normalized to the K-band flux.
