The absolute calibration of the extended emission observed by IRAS was based directly on the absolute calibration of the point sources. Thus the value of the equivalent absolute flux density assigned to the flashes of the internal reference source was carried directly to the calibration of the extended emission with the additional corrections for the frequency response and effective detector areas; see Sections IV.A.3 and IV.A.4.
