Left: conversion factor from observed flux (in mJy) to L_IR (in units of 12¹²L_⊙). Right: conversion factor from observed flux (in mJy) to a dust mass (in units of 10⁸M_⊙). The top panels give the associated relative uncertainty on the conversion. These data are tabulated for easier access in Tables A.1 and A.2, respectively. These factors are provided for all ALMA bands from band 8 to band 3, assuming the standard frequency.
