Left: full multiwavelength photometry for HD 172555, including new mm photometry (colored symbols) from our observations. Right: zoom-in from the left panel focusing on ALMA (sub)mm data. In both panels, diamonds correspond to the higher spectral setup and squares correspond to the lower spectral setup. Dark orange markers are stellar fluxes, blue markers are disk fluxes, and dark green markers are total (disk and stellar) combined fluxes. Error bars are 1σ. Previous photometric measurements are in black, where circles are detections and downward-facing triangles are upper limits (photometric points are listed in Table B.1). The best-fit star (orange, solid) and single-component modified blackbody disk (blue, dash-dotted) models are included and obtained using the method from Yelverton et al. (2019).
