+//   1) Zero scan rate pairs, 1997/02/28 to 1998/01/07
+//
+//      These occur because the position timestamp for the first integration

+//        (time range chosen to encompass observing runs).

+//   2) Slow-fast scan rate pairs (0.013 - 0.020 deg/s),
+//        1997/03/28 to 1998/01/07.
+//
+//      The UTC position timestamp is 1.0s later than it should be (never
+//      earlier), almost certainly arising from an error in the telescope
+//      control system.
+//        Earliest known: 97-03-28_0150_010420-74_008d.hpf
+//          Latest known: 98-01-04_1502_065150-02_177c.hpf
+//        (time range chosen to encompass observing runs).
+//
+//   3) Slow-fast scan rate pairs (0.015 - 0.018 deg/s),
+//        1999/05/20 to 2001/07/12 (HIPASS and ZOA),
+//        2001/09/02 to 2001/12/04 (HIPASS and ZOA),

+//      Caused by the Linux signalling NaN problem.  IEEE "signalling" NaNs
+//      are silently transformed to "quiet" NaNs during assignment by setting
+//      bit 22.  This affected RPFITS because of its use of VAX-format
+//      floating-point numbers which, with their permuted bytes, may sometimes
+//      appear as signalling NaNs.
+//
+//      The problem arose when the linux correlator came online and was
+//      fixed with a workaround to the RPFITS library (repeated episodes
+//      are probably due to use of an older version of the library).  It
+//      should not have affected the data significantly because of the
+//      low relative error, which ranges from 0.0000038 to 0.0000076, but
+//      it is important for the computation of scan rates which requires
+//      taking the difference of two large UTC timestamps, one or other
+//      of which will have 0.5s added to it.
