The charges from the ACC are followed by comments abstracted from
a longer response from P. Cox, ASAC Chair.

1. The ASAC is asked to evaluate all available site (225 GHz opacity, 12
GHz phase stability, 350 micron and >1 THz) data for Chajnantor, and
to discuss any significant trends and issues which may impact the scientific
mission, design or mission emphasis of the baseline instrument.
 
	Neal Evans will be leading the work on this Charge.
        He will work with Sakamoto, Radford and Lucas and perhaps others.

2. The ASAC is requested to make an assessment of ALMA early science. What
kinds of scientific data (including the balance between spectroscopic and
continuum data) are likely to be most desired as ALMA begins operations?
Based on this probable interest, what are the commissioning and operational
implications for the array's baseline capabilities, frequency coverage and
operating modes?

        To be discussed in close contact with the Project Scientist, 
        Stephane Guilloteau. P. Cox volunteered to take part in this 
	group, and Ewine van Dishoeck would like to be included/kept 
	in the loop in the discussions.  Al Wootten, Ken Tatematsu and Hiroshi 
	Matsuo will participate in this working group.

3. The ASAC is requested to summarize the scientific and technical issues
associated with the long baseline array geometries currently under
consideration and to advise the ACC/ad hoc ALMA Board as to possible cost,
land use, and land access impacts of which it should be aware.

        Mark Holdaway is currently
	working on a new memo on the Y+ long-baseline configuration,
	specifically on the reconfiguration possibilities and the 
	question of resolution. This memo will be available very soon. 

4. The ASAC is requested to reassess the list of prioritized enhancements
that Japan should be asked to contribute to the baseline ALMA instrument,
understanding that Japanese participation in ALMA is likely to be proposed
at a level significantly below that of North America and Europe in the
baseline project. The ASAC should take into account the fact that given the
schedule, these enhancements are to be contributed by Japan and cannot be
redistributed among the partners.

	The reconsideration of the prioritization of the enhancements to
	the Baseline Project is clearly a matter of the ASAC as a whole, 
	with a recommendation to be made at our face-to-face meeting. 	
	Since this topic was discussed in detail in the Oct. 2001 report
	(although in an context, with different boundary conditions)
	it was suggested that Ewine van Dishoeck and Geoff Blake (Chair 
	and co-Chair Persons at that time) be part of a smaller group 
	leading the discussions. It was also suggested that the ex-ALG 
	liaison members, i.e. Neal Evans and myself participate.  
	Ken Tatematsu and Hiroshi Matsuo, who made substantial 
	contributions in the preparation of the cases of Band 8 and 10 
	will also participate in this working group. Satoshi Yamomoto 
	will summarize the japanese view and send a memo to the ASAC 
	as soon as possible. This document should serve as the basis 
	for our discussions.
