Dereddened optical IPHAS, 2MASS, and GLIMPSE photometry for the IPHAS-selected A-type stars with excesses at 8 μm and 24 μm (blue triangles with error bars denoting the 1σ photometric error of each measurement). For each star, the red solid line corresponds to the reference photospheric SED normalised to the K-band flux. The pink dotted line represents the blackbody that, added to the stellar SED, minimizes the χ ² fit to the data (solid green line). Only the 2MASS and GLIMPSE data points were included in the best-fitting routine.
