1991ApJ...372..380Y A REDSHIFT SURVEY OF IRAS GALAXIES. II. METHODS FOR DETERMINING SELF-CONSISTENT VELOCITY AND DENSITY FIELDS AMOS YAHIL Astronomy Program, State University of New York, ESS Building, Stony Brook, NY 11794-2100 MICHAEL A. STRAUSS AND MARC DAVIS Astronomy and Physics Departments, University of California, Berkeley, CA 94720 AND JOHN P. HUCHRA Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138 Received 1990 July 16; accepted 1990 October 19 ABSTRACT Methods are presented for deriving the density field and the resulting linear-theory velocity field from an all-sky redshift survey of IRAS galaxies. The luminosity function of IRAS galaxies is measured using a maximum-likelihood technique independent of density inhomogeneities. Within its range of validity, it is found to be in excellent agreement with previously published luminosity functions. Self-consistent solutions for the true spatial positions of the IRAS galaxies are found, given their redshifts and peculiar velocities. The ambiguity inherent in triple-valued regions is overcome either by sufficient smoothing, or by using prior information from peculiar velocity maps obtained independently. Subject headings: galaxies: redshifts - infrared: sources - luminosity function ############################################################################# 1991ApJ...381..348Y ERRATUM In the paper, "A Redshift Survey of IRAS Galaxies. II. Methods for Determining Self-consistent Velocity and Density Fields" by Amos Yahil, Michael A. Strauss, Marc Davis, and John P. Huchra (ApJ, 372,380 [1991]), Figures 14 and 15 were presented out of order, with their legends reversed. Thus, the figure at the bottom of page 391 is Figure 15, and should have the legend: "Fig. 15.-As in Fig. 13, for the method 3 results." The figure at the top of page 392 is Figure 14, and should have the legend: "Fig. 14.-Plot in Galactic coordinates of the quantity V_diff_ for galaxies within 3000 km s^-1^ of the LG. The symbol size is proportional to V_diff_ - 400 km s^-1^, which measures the deviation of the redshift- distance relation along the line of sight to that galaxy from pure Hubble flow."
