asap has trouble reading in time-binning files

[StacyMader]

asap v4.0.0 on OS X 10.6.8

It seems asap has trouble reading in observations done with the Parkes DFB in time-binning mode. asap reports: Multiple IFNOs in FREQ_ID = 0 !!! for the attached file which contains two IFs (both the same frequency).

ASAP>sc=scantable('2012-03-11_2304-P000_METH6_Tsys.rpf',average=False)
Cross polarization present

Requested JD 55998 is outside the IERS table data range.

I forgot to add, if one selects the IFs manually,

sel=selector() sel.set_ifs(1) scan.set_selection(sel) scan.summary()

The data are reported as required, so when initially loading in the data and displaying scan.summary(), it seems to be just a reporting issue.
