+* ``randseisdata()``: Generate a SeisData structure with pseudo-random headers and data. Specify ``c=false`` to allow campaign-style channels with ``fs=0``. Specify an integer argument to set the number of channels; otherwise, ``S.n`` varies from 12 to 24.

 * ``sync!, sync``: Synchronize time windows for all channels and fill time gaps. Calls ``autotap!``, which in turn de-means and calls ``ungap!``.
 
-* ``ungap!, ungap``: Fill all time gaps in each channel of regularly sampled data.
+* ``ungap!, ungap``: Fill all time gaps in each channel of regularly sampled data. By default, ``ungap`` invoked alone will cosine taper non-gap subsequences of time series data (keyword ``w=true``), and will fill time gaps with the mean of non-NaN data points (keyword ``m=true``). These behaviors can be changed by changing the keywords corresponding to each.

 ***********************************
 A few utility programs are included with SeisIO.
 
-``plotseis(S)``: Plot time-aligned trace data from SeisData structure ``S``.
-
-``randseisdata()``: Generate a SeisData structure with pseudo-random headers and data. Specify ``c=false`` to allow campaign-style channels with ``fs=0``. Specify an integer argument to set the number of channels; otherwise, ``S.n`` varies from 12 to 24.
-
-``randseisobj()``: Generate a Seisobj structure with pseudo-random headers and data.
-
 ``getbandcode(fs, fc=FC)``: Generate a valid FDSN-compliant one-character band code for data sampled at ``fs``; corner frequency ``FC`` is optional.
 
 ``tx = t_expand(t)``: Expand sparse delta-encoded time representation ``t`` to generate time stamps for for each value in the corresponding data ``x``.
