  skos:definition """The Michelson Doppler Imager (MDI) is a project of the Stanford-Lockheed
Institute for Space Research and is a joint effort of the Solar Oscillations
Investigation (SOI) in the W.W. Hansen Experimental Physics Laboratory of
Stanford University and the Solar and Astrophysics Laboratory of the
Lockheed-Martin Advanced Technology Center. The MDI is flown on the Solar 
Heliospheric Observatory (SOHO).

The Michelson Doppler Imager is capable of making a wide range of observations
within the constraints imposed by the instrument design, by telemetry
availability, and by the limits associated with the running observing programs.
This page summarizes the instrument observables and the nature of the observing
programs. It is intended to provide sufficient background for potential
proposers of research investigations involving either special observations or
the analysis of standard program observations. For a full description of the
instrument capabilities and mission observing plans, see The Solar Oscillations
Investigation - Michelson Doppler Imager (Scherrer et al., Solar Physics. in
press).
