[daip] FITS-IDI files with > 5 days worth of EOPs

Hi DAIP,
Within the DiFX community we wish to change the way in which we handle EOP
values to simplify cases where a single experiment is longer than about 2
days. Currently based on historical hardware correlator behavior we have
been restricting the model generation to use only 5 days of EOP values.
We would like to allow an arbitrary (or at least large upper limit, maybe
100) EOP values to be used. A standard cubic spline is used in CALC to
evaluate the EOP values at an arbitrary point in time; that won't change.
Will increasing the number of EOP values transmitted to AIPS via FITS-IDI
be OK? Will programs that use the EOP values (I only know of the one that
does a correction for bad EOPs) properly cope?
Thanks,
Walter
