Abstract:
     We present extensive CO (J = 2-1) survey data of the first quadrant
  of the Galaxy taken with the same angular resolution as the Columbia
  CO (J = 1-0) survey.  The CO (J = 2-1) data were compared with the CO
  (J = 1-0) data of Cohen, Dame, & Thaddeus [1986, ApJS, 60, 695].  The
  distribution of CO (J = 2-1) emission mimics that of CO (J = 1-0)
  emission with the CO (J = 2-1)/CO (J = 1-0) intensity ratio (defined
  as R_(2-1/1-0)) of 0.66 averaged over the observed area.  This value
  is typical of nearby giant molecular clouds and of gas disks of spiral
  galaxies and is consistent with the CO emission arising from
  subthermally excited, optically thick gas.  Molecular gas in the inner
  part of the Galaxy tends to exhibit a higher value of R_(2-1/1-0) than
  in the solar neighborhood.

Description:
  The files in this directory are ASCII tables of the l-v diagrams of
  the Tokyo-NRO CO (J=2-1) survey of the Galactic plane.  All the data
  have been resampled in velocity so that they match the CO (J=1-0) data
  of the Columbia survey.  Intensity has been scaled by a factor of
  1/0.93 (eta_mb=0.93) to get the main beam brightness temperature
  averaged in each velocity bin.

  The table data listed below, as supplied by the author, are not in a
  format that is conducive to reformatting into FITS, with object header
  records and data records that can only be described by using field
  format repitition factors (which are not allowed in FITS ASCII tables).

  Each data file is formatted as follows:

  Line 1:     2376 bytes (no difference among 9 data files)
              LSR velocity (km/s, F9.5-F7.5) x 256
              field separator: TAB x 257
              (including at the beginning and the end of the line)
  Line 2-162: 3080 bytes
              Galactic longitude (deg, F8.5), Tmb[CO(J=2-1)] (K, E11.3)) x 256
              field separator: TAB x 256
