Comments:
(*1) The unit um0007 contents the observations from the units um0001, um0002, um0003,
but the data are reduced to the ICRS system.
(*2) Some of the observations from unit um0007 published by Veiga et al. were excluded
since they were republished in 2015 by Camargo et al. 2015.
(*3) Many observations made in the portion 0128 are the result of reprocession of observations
contained in um0085.txt, um0086.txt, um0102.txt, and um0103.txt.
The data were reprocessed by using the UCAC4 catalogue.
