[daip] something weird in CLCOR

[Claire Chandler]

Chaps,

When I try to apply a small position correction to data using CLCOR the
new position in the SU is not what I expect:

The original position in SU table is

   2 BNKL-I          : 0000         05:35:14.5098 -05:22:30.482  580562

CLCOR is run with the following inputs:

AIPS 1: Keyword = 'SOURNAM1'  value = 'BNKL-I  '
AIPS 1: Keyword = 'SOURNAM2'  value = '        '
>tget clcor
>inp
AIPS 1: CLCOR     Task which applies various corrections to CL tables.

AIPS 1:            *rest 0
AIPS 1: BADDISK    *all 0                  Disks to aviod for scratch

and the output position in the SU table is:

   2 BNKL-I          : 0000         05:35:14.5041 -05:22:30.272  580562

when I'd have expected the declination to be more like -05:22:30.382.

Is this just a rounding error, or something more serious?
