J/ApJS/70/329    IRAS flux densities for early-type galaxies  (Knapp+ 1989)

Description: (Abstract of the paper)
    The data from the IRAS satellite were co-added for about 1150
    early-type galaxies with apparent magnitudes brighter than 14mag.
    At 60 and 100micro meter, about 45% of the ellipticals and 68% of
    the S0 galaxies are detected, showing that a large fraction of
    these galaxies contain cool interstellar matter.

Notes:
  * The catalogue archived here is the Table 2 of the paper.
    Note that the flux data have been changed slightly from those in
    the paper.

  * Four typographic errors have been corrected, i.e. N5195, columns 48 and 57;
    N0560, column 74; and N0564, column 74.

  * Following description was originally attached to the software "calc.for":
   "The data for 1153 galaxies are in 'table2'.
    The columns are as in G.R.Knapp et al. 1989, ApJ Suppl 70, 329.
    The IR flux densities are in Jy, the 1 sigma noise in mJy.  These
    are *NOT* corrected for the scale differences.  The program 'calc.for'
    (see the source deck of 'calc.for') does this, rounds them off, and
    performs various manipulations to the optical magnitudes that the user
    may or may not care about.
       The redshifts are from
     RC2 (Sec.Ref.Cat., deVaucouleurs)
     RSA= Rev. Shapley-Ames, Sandage & Tammann 1981, Carnegie
     Davies et al. (see Burstein et al. 87, Ap.J.Suppl. 64,601
                       ('7 Samurai'))
     ZCAT = CfA redshift survey (J.P.Huchra, priv.comm.) "

  * The software "calc.for" needs two input files, i.e. "table2" and
    "types.dat". The latter is not archived here.

  * Performance of the software has not been well tested in CDS.
