Abstract:
ALMA will provide a tremendous advance in sensitivity and resolution at
millimeter wavelengths--about two orders of magnitude over existing
arrays. Additionally, unlike existing array practice, ALMA images will
contain all of the flux emitted from astronomical objects, achieving
excellent image fidelity. ALMA's advances in in sensitivity,
resolution and image fidelity require that ALMA also have as a goal an
advance in calibration accuracy. In this session we will discuss the
calibration plan which is emerging to attempt to meet this goal.

(Note: this is not strictly speaking a "calibration" topic,
but is closely enough related that I thought we should
include it)

(Note: there is an entire session on WVR issues in the afternoon
on Friday June 6, so most discussion related to that topic will
be deferred to that session)
