Hi Glen:
    Both bugs are general to all the 4GHz mode data.
The bug in the uvlist can be simply fixed by increasing the limit of
spectral windows. To get rid of the second problem in mapping (invert),
either set options=flagch0 in smalod or using uvflag to reset
the flag states for channel 1 (window 1):
uvflag vis=100727_11:33:23_rxl.lsb select='window(1)' flagval=unflag
    There was a bug in options=flagch0 of smalod.
    Both bugs have been fixed and a new beta version (1.1.0) has been
released. Please ask Ram to get the updated miriad from
http://www.cfa.harvard.edu/sma/miriad/download/
and install it. Then please give a try again.
    Thanks.
