ALMA Memo No. 366

A Telescope Pointing Algorithm for ALMA

J. G. Mangum (NRAO Tucson)

04/30/2001

The stringent pointing specification of 0.6 arcseconds for the ALMA
antennas places some strict requirements on the ALMA pointing model
formalism.  In this document we:

- Describe the basic pointing model formalism used at most radio
  telescope observatories;
- Present a detailed analysis of the atmospheric refraction
  correction used in this model;
- Suggest a form for the refraction correction and associated
  weather parameter measurement sensitivity which will meet the
  ALMA pointing requirement;
- Suggest a structure for the pointing coefficient information for
  each antenna.
