Roy,
I'm all for that! Let's make some necessary modifications to UCD1 and start using them. I went through examining the ERROR 'box', assuming that each ERROR could be transformed to "error.QUANTITY_UCD". It works most of the time, but there are some cases where it simply doesn't work. Bottom line is that in Vizier's metadata there are around 9000 ERROR columns, which translate into about 570 new error descriptors.
Assuming what we want to do is to "change the labels" from UCD1 to UCD_N, then we will preserve the degree of comparability. If we start shuffling columns from one box to another, and merging boxes, then the work will be much more!!
Cheers,
Patricio
