CHANGES in Version 1.2:
-----------------------------------------------------------------
1/f gain fluctuations can be added to the simulated WVR data in
the function wvrsim.addwvrdrift()

Interface to the function wvrsim.addwvrnoise() has changed, permitting
the user to scale the thermal noise.

A function state() has been added to both wvrsim and wvrreduce so that
the user can see the internal details of these tools.




		This package contains:
------------------------------------------------------------------

		Package Documentation

wvr_user.ps		A user's guide to setting up the simulation
			package and running it.

wvr_user.tex		Source for the user's guide.

------------------------------------------------------------------

		Code

wvrsim.g		Glish/AIPS++ code which defines the wvrsim
			tool.  This tool simulates observing through
			a model atmosphere.  Several test procedures
			and stand alone functions are also defined
			in this file.

wvrreduce.g		Glish/AIPS++ code which defines the wvrreduce
			tool.  This tool processes and evaluates the
			simulated data.

oneoverfnoise.g		Glish code which defines the 1/f noise tool.
			1/f gain fluctuations can be added to the
			simulated WVR data.

almasensitivity.g	Glish/AIPS++ code which defines the
			almasensitivity tool.  This estimates the noise
			level for various ALMA observations.  This
			script is not used explicitly by the wvr code,
			but may be of help to the user who wishes to 
			use realistic noise levels.

almatau.g		Glish/AIPS++ code which encapsulates the
			opacity as a function of PWV and frequency
			(taken from ATM), and is used by 
			almasensitivity.g.

------------------------------------------------------------------

		Atmospheric Transmission Code

am			The executable for Scott Paine's Atmospheric
			Model. This executable is called repeatedly by
			wvrsim.letitroll() and forms part of the core
			functionality of the package.

am_manual.pdf		User's manual for the am code.  You don't need
			this to use the wvrsim code, but am is
			generally useful, especially if you know how
			to drive it.

			Scott Paine can be reached at 
			<spaine@cfa.harvard.edu>  The am code and
			manual are included with Scott's permission.

------------------------------------------------------------------

		Data

TEST_ATMOS/		A directory containing ASCII arrays of
			atmospheric pressure, temperature, and water
			vapor pressure.  This is the test atmosphere 
			we built the package around.

atmos.tab/		The AIPS++ Table version of the test
			atmosphere.  (Note that the files in 
			TEST_ATMOS/ can reproduce atmos.tab/)

ants/			A directory of example antenna configuration
			files.
