Attending:
----------
AOC: Brisken, Brogan, Chandler, Golap, Myers, Taylor, McMullin, Kemball
CV:  Fomalont, Hibbard
GB:  Moellenbrock

Notes:
------
o AIPS++ development
	There have been 67 defects resolved in the last month (14 from NAUG
	members). In a subsequent discussion, we decided that NAUG members
	should report on the results of resolved defects if it is of general
	interest. In this spirit, Hibbard brought up some recent changes in the
	image profile fitter, specifically the gaussian fitter which allows
	the user to save gaussian fits to use as future guesses and to view
	the gaussians independently for multi-gauss fits.

	Some recent development items of interest. 
	cvsup capability has been expanded to also include docs as well
		as data.
	A 3-d source finder and fitter has been implemented in the image
		tool.
	Weights have been added to sundry fitting utilities. 
	A new drag event is used in the image analysis tool in the viewer.
		You can now see the spectral profiles in your cube as you
		move the cursor around.
	Defect list will be sent to Fomalont each month. McMullin will give 
	a DDTS demo as necessary at the next NAUG meeting.

o Summer School
	The summer school data has been checked into the data repository
	and is now available at all AIPS++ consortium sites through:
	/aips++/data/nrao/VLA/ngc5921.fits
	                      ngc5921_ch0.fits
                              planets_6cm.fits
	
	The first draft of the cookbook has been produced (Moellenbrock);
	this will serve as the focus for the efforts in different areas
	(calibration/imaging/etc) for the next few months. The time table
	for the summer school is the following:
				April 24: NAUG meeting:general discussion
					  on cookbook; assess schedules of
					  NAUG members for summer school
					  and for tutorial training.
				May 8   : AIPS++ demonstration of tutorial
					  on reduction
				May 22  : NAUG meeting: count of members
					  comfortable giving AIPS++ tutorial
			 	June 18 : Beginning of summer school. Based
					  on the sign-ups, Taylor will assess
					  tutor needs for AIPS++.
				June 21 : Tutorials.

o The AIPS++ release cycle draws to a close on May 16th. Release notes should
	be prepared by that date. The NAUG will again be involved in helping
	to draft this.

o Review targets:
	Most targets are under active testing. The high frequency calibration
	and spectral line calibrater targets are awaiting AIPS++ action.
	Golap is nearly ready to check-in imager interactive mask work.
	Fomalont discussed the imagefitter briefly. There is an existing 
		problem with the error estimates (defected).
	The viewer review has been completed by the NAUG and submitted to
		AIPS++. Many of the items are being worked on this development
		cycle. Others will need to be rolled into the NAUG's list
		of priorities for the next cycle.
	Execution efficiency is being worked on between Kemball and Fomalont.

o Other
	Brogan had several recommendations for the imager gui. In particular
	to create a group which represents a logical process for image
	production; it would be a small subset of the full functionality
	consisting of the 'most commonly used' functions. This was regarded
	as an improvement by all, with an overall discussion of how to limit
	the exposure of users to a 'core' subset of the package. In addition,
	Brogan wants to suppress the GUI representation of tools universally
	deemed 'bad', a.k.a. map. This will also be done (on a case by case
	basis). Brogan will circulate her list of the 'basic' imager group
	functions (done). Much jocularity ensued.
