  ** This subdirectory holds the most recent tables:

    2088-day MDI  l=1 to 125 (*)
    2088-day GONG l=1 to  25
     728-day MDI  l=1 to  95,  9 overlapping segments (Jan 2008)
     728-day MDI  l=1 to  50,  9 overlapping segments (Sep 2007)
     728-day GONG l=1 to  25,  9 overlapping segments
     364-day MDI  l=1 to  25, 19 overlapping segments
     182-day MDI  l=1 to  25, 39 overlapping segments

following the fitting method described in [2005ApJ...626..585K].

(*) Caveat emptor: Low frequency modes (frequency < 1 mHz and the f-mode) for
    the 2088-day-long MDI fitting are to be viewed WITH SUSPICION - this is
    'work in progress', and are MOST LIKELY to be recomputed & updated!

Note: The error bars still need to be fine-tuned, esp. at very low frequency.

  ** Send me an email if you want to be notified when tables are updated.

  ** Look at the file FORMAT for format details.

  ** Organization:

       Nd/Nd.sS.I.L0.L1.dat 

       where: 
          N: time-serie length (2088, 728, 364, 182)
          S: segment no (01, 02, ...)
          I: instrument (gong or mdi)
          L0, L1: l range fitted

     Nd.tgz is the tar-gzip'd content of Nd/, (N = 2088, 728, 364, 182)

  ** The 728-day long segments ranges:

Ranges for the 364-day and 182-day long segments are derived by halving (or
quarting) the above listed segments.
