Abstract:
     A K'-band imaging survey with a ~8'x3' field of view of all regions
  associated with CO molecular outflow from the list of Fukai (1989) has
  been conducted.  We present the individual images and describe
  individual nebulous objects and star clusters.  The data, including
  photometric calibration data, are being published as FITS files on a
  CD-ROM.
     The vast majority of all outflow sources are associated with
  nebulosity detectable in K', so such nebulae can be used as tracers
  for very young stars.  We find a significant fraction (one-third) of
  molecular outflow sources to be associated with clusters of young
  stars.  Most of the young embedded clusters show peaks in their K'
  magnitude histograms that, if interpreted as an evolutionary effect,
  indicate average ages of the embedded star population of <1x10^6 yr.

Description:
  The primary data for this paper consists of 232 FITS images
  containing the imaging data and frames of the standard stars.  The
  standard star images are 60x60 pixels frames with the star
  approximately centered on the frame.  The first seven characters of
  the standard star file names contain the name of the star, sometimes
  abbreviated.  The last character of the file name (A, B, C, ...)
  distinguishes different frames of the same star.  The exposure time
  (limited by the external shutter) is given in the file headers.  The
  standard stars include GL 347A, HD 3029, HD 18881, HD 22686, HD
  161903, HD 162208, HD 201941, HD 203856, and HD 225023.  Object
  names, coordinates, file names and other pertinent information for
  the program objects are given in table 1 described below.
