We need both.  CRVAL1 is a decimal number, RA is human readable.  
It does no harm to "double up" headers and include both UT and
UTSTART.  even if the associated values are identical.  Each FITS
reader will find the line it wants.  To make the most number of
readers happy you have to includes quite a few lines.  FITS readers
ignore lines they don't understand.
