Plans for initial VTT release
=============================

Assumptions
-----------
We are proceeding under the following assumptions:

1) The VTT that will be released on June 1 will be used for Phase 1
work; it will not be ready for Phase 2 work. There will not be an
encompassing APT (or SEA) at this time.

2) The bugs in the system and the ramp up time for the developers will
preclude most enhancement work for the June 1 release. Exceptions will
be made for very minor changes on a case by case basis.

3) This VTT is still a prototype and will be developed, tested,
documented and released as such. This means:

	a) The developers will be testing their own bug fixes.

	b) Several iterative releases will be made for testing
	purposes.

	c) Only two platforms will be supported: Solaris and NT.

	d) Independant testing will focus on usability problems
	and problems that would affect Phase 1.

Test plan
---------

Talk to Jeremy to determine most critical things to test 

Determine use cases/requirements for VTT in Phase 1 

Find existing observations in the archive to "plan" in the
VTT and compare the results

Compare VTT FOV to SPSS FOV
 
Review the procedure for displaying each type of aperture using data
from the SCIOPSDB (get help from John Baum)


High level use cases for the VTT in Phase 1
-------------------------------------------

1) How many exposures will I need to mosaic my extended target?

2) Which of my potential targets "fits best" in the aperture.

3) Would a coordinated parallel in another aperture provide
additional data related to the science in my proposal?

4) Do any of my potential targets have nearby bright objects that
could spoil the observation? Is there an orient which would avoid the
bright object?

These uses imply that we need to verify to "eyeball" accuracy:

A) The size, shape, fiducial point, and relative placement of the
supported and available apertures.

B) The ability of the VTT to scale the FOV to various images
correctly.

C) The ability of the VTT to place the fiducial point of the chosen
aperture correctly with respect to the requested pointing on the
selected image.
