We are having trouble processing VLBA data taken during the summer of 2014. The VLBAEOPS procedure appears to pick up bogus information and exactly no corrections are made. Here is the log of the process for data 2014august 10:

LOCALH> CLCOR1: Copied CL file from vol/cno/vers  1  103   2 to  1  103   3
LOCALH> CLCOR1: CL version input   2 output   3
LOCALH> CLCOR1: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
LOCALH> CLCOR1: !  OPTYPE=EOPS is used for proper CT tables only !
LOCALH> CLCOR1: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
LOCALH> CLCOR1: UT1-UTC(sec), POLX, POLY(milliasec) used by correlator
LOCALH> CLCOR1:     1  -2. -0.316470   202.130   371.240
LOCALH> CLCOR1:     2  -1. -0.316695   203.120   370.190
LOCALH> CLCOR1:     3   0. -0.317088   204.250   369.170
LOCALH> CLCOR1:     4   1. -0.317688   205.430   368.340
LOCALH> CLCOR1:     5   2. -0.318441   206.490   367.630
LOCALH> CLCOR1: ZTXOP2: using translated file name =
LOCALH> CLCOR1: ZTXOP2: /tmp/usno_finals.erp
LOCALH> CLCOR1: UT1-UTC(sec), POLX, POLY(milliasec) picked up from the USNO file
LOCALH> CLCOR1:     1**********  ********************************
LOCALH> CLCOR1:     2**********  ********************************
LOCALH> CLCOR1:     3**********  ********************************
LOCALH> CLCOR1:     4**********  ********************************
LOCALH> CLCOR1:     5**********  ********************************
LOCALH> CLCOR1:   4205 Records modified

We have processed the data from this point to the end and this phase referencing experiment appears to fail without the EOPS corrections.

An earlier processing of the same data performed in the fall of 2014 worked fine. However we need to reprocess the data at this time.

Thanks in advance for your help,

Dave Roberts
