TOPO RELEASE NOTES

------------------------------------------------------------------------
Version 2.05, released 2-September-2000
------------------------------------------------------------------------

This is a maintenance release, with some small changes to PROF2PSD,
SURF2PSD, SURF2AVE_PSD, and PSD2RAVEPSD (as described in topo.html),
as well as support for IDL 5.1 and higher.  With any luck, this
version of IMD will work with IDL releases beyond 5.4.  But we'll
see...

------------------------------------------------------------------------
Version 2.04, released 1-December-1998
------------------------------------------------------------------------

Minor changes to PROF2PSD, SURF2PSD, and RD_DIGITAL_AFM, as
described in topo.html

------------------------------------------------------------------------
Version 2.03, released 5-June-1998
------------------------------------------------------------------------

Major changes:

Added PSD2RAVEPSD, to compute radially-averaged PSD functions from 2D
PSD arrays.

Added new PSD fitting functions, PSD_SIGMA_XI_H_FIT and
PSD_OMEGA_NU_N_FIT, intended to fit radially-averaged PSDs. PLOT_PSD,
has been updated to make use of these new PSD functions.

Added a new widget application, XANLZ_PSD, for fitting 1D PSD
functions.

The radially-averaged PSD, and the X- and Y-averaged PSDs can be
computed and analyzed (via XANLZ_PSD) directly from the new Analysis
menu on the XANLZ_SURF program.

It's now possible to control precisely what's plotted when using
ANLZ_PROF (with the PLOT keyword) and XANLZ_PROF (with the buttons on
the main widget.)

RD_MICROMAP and RD_ZYGO have been added.

RD_DIGITAL_AFM is now actually working.

Added extras.dir directory, which includes files necessary to use TOPO
as a XOP extension, and example data files.

Many bugs fixed.  

------------------------------------------------------------------------
Version 2.02, released 12-January-1998
------------------------------------------------------------------------

Minor changes to XANLZ_SURF and ANLZ_PROF, in order to properly
produce HP and CGM output (both of which are now available due to
changes to the PLOT_PRINT routine.)

------------------------------------------------------------------------
Version 2.01, released August 1997
------------------------------------------------------------------------

Added SWAP_ENDIAN keyword to the RD_WYKO function.  The
'wyko_example.dat' file can now be read on Windows platforms by making
use of this feature.
