# Examples:
# Reference of the redshift => meta.ref
# Field center decl for J2000 => pos.eq.dec;meta.main, Problem: meta.main doesn't exist in the context; the shortage "decl" is not found, must be "declination".
# H selected default magnitude => phot.mag;em.IR.H, Problem: "em.IR.H" not in the context, because the token "h" is lower case and the ucd is upper case.
#Proper motion in RA => pos.pm;pos.eq.ra


#Uncertainty flag on V-I (1) => meta.code.error;phot.color;em.opt.V, Problem: to get phot.color in the context, there needs to be a rule that adds "phot.something" to the context if em. is there as well.
