[daip] Fittp/Fitld impact on indxr

[Amy Mioduszewski]

Hi Arnaud,

Eric asked me to try to help you since I am more of a vlbi expert.  Could you 
send me your USUBA inputs?

Thank you,

Amy

>> SC and SC_VLBA are recognized but SAINCROI, STCROIX, StCroix, etc etc are not.  Computers recognize strings literally not by mental association.  The association algorithm would be to look for SC anywhere in the string but are there no stations with an SC in the name somewhere?   If correlators just make up names for the stations and change them all the time, we are not able to list them all.  I can add some more but you will note that PIETOWN is not in the pattern of all the other VLBA names - somebody is just making things up for the fun of it.
