MAXCHAN  = 6144**    (maximum channels per bl, sb, rx, pol)
   MAXANT   = 8         (maximum number of antennas for the standard SMA)
   MAXBAS   = 112       (maximum number of baselines =
                         MAXANT*(MAXANT-1)/2*2rx*2sb)
   MAXINT   = 10,000    (maximum number of integration scans = 
                         13.9h for 5s integration) 
   MAXSCHAN = 4096      (maximum channels per spectral window (chunk))
   MAXCHUNK = 24        (maxmimu number of spectral windows per side band)
   MAXSRC   = 100       (maximum number of sources per track,
                         about 8.3min per source in a 13.9h track)
   MAXRX    = 2         (maximum number of rx per track)

**This is the value (24*256=6144) for the standard array with 8 antennas.
In the past, a few tracks might have broken this limit for super high
spectral resolutions in an array with a number of antennas less than 8. 
In Miriad, a larger number for this parameter (MAXCHAN=4*6144=24,576) 
has been adopted for assuring problem free in handling SMA data.
