ALMA Week Main Page

Main ALMA Week 2003 Page

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.

Date, Time, Place:
Date: Thursday, June 5
Time: 13:30 - 17:45
Room: Small Meeting Room 1
Chair: Al Wootten


   5m  Introduction   Butler

  10m     Receiver Gain Stability   Guilloteau
          (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)
