Box 50727, 28080 Madrid, Spain and Ingolf Heinrichsen Cong Xu Infrared Processing and Analysis Center, MS 100-22, 770 South Wilson Avenue, Pasadena, CA 91125 Received 2001 July 15; accepted 2001 October 9 ABSTRACT We present deep diffraction-limited far-infrared (FIR) strip maps of a sample of 63 galaxies later than S0 and brighter than B_T_ = 16.8, selected from the Virgo Cluster Catalogue of Binggeli, Sandage, & Tammann. The ISOPHOT instrument on board the Infrared Space Observatory was used to achieve sensitivities typically an order of magnitude deeper than IRAS in the 60 and 100 micron bands and to reach the confusion limit at 170 microns. The averaged 3 {sigma} upper limits for integrated flux densities of point sources at 60, 100, and 170 microns are 43, 33, and 58 mJy, respectively. A total of 63.5% are detected at all three wavelengths. The highest detection rate (85.7%) is in the 170 micron band. In many cases the galaxies are resolved, allowing the scale length of the infrared disks to be derived from the oversampled brightness profiles in addition to the spatially integrated emission. The data presented should provide the basis for a variety of statistical investigations of the FIR spectral energy distributions of gas-rich galaxies in the local universe spanning a broad range in star formation activity and morphological types, including dwarf systems and galaxies with rather quiescent star formation activity.

Tuffs, Cristina C. Popescu, Daniele Pierini, and Heinrich J. Volk Max-Planck-Institut fur Kernphysik Hans Hippelein Max-Planck-Institut fur Astronomie Kieron Leech and Leo Metcalfe ISO Data Center, Astrophysics Division and Ingolf Heinrichsen and Cong Xu Infrared Processing and Analysis Center The legends for Figures 9 and 10 were switched. The legend for Figure 9 should read: "Uncorrected {chi}^2^ values derived from fitting the Gaussian models to the maps vs. the corresponding flux densities at 60 microns obtained from integrating the model fit to infinity. The data were plotted as diamonds, except for those galaxies for which the model was an imperfect fit to the data, which were plotted as crosses. The solid line rising for F_60_ > 1.5 Jy represents the linear correlations between flux and {chi}^2^, as a result of systematic errors due to the oversampling in cross-scan direction. For faint flux densities {chi}^2^is dominated by systematic errors, producing a clumpy distribution at the left-hand side of the plot, with a lower envelope, which we traced by a solid line to guide the eyes." The legend for Figure 10 should read: "Model fits to the observed brightness profiles of all the Virgo galaxies from our sample (except for the interacting system VCC 1673/VCC 1676; see section 6.2.4). Statistical uncertainties for selected map pixels near the extremities and center of the scans are indicated by the 3 {sigma} error bars. The legend is as in Fig. 8." In addition, the references to Figures 9 and 10 in the main text should be interchanged. The Press sincerely regrets this error.
