Moog may refer to:

Moog is a 2004 documentary film by Hans Fjellestad about electronic instrument pioneer Dr. Robert Moog. The film features scenes of Dr. Moog interacting with various musical artists who view Moog as an influential figure in the history of electronic music.

Moog is not a comprehensive history of electronic music nor does it serve as a chronological history of the development of the Moog synthesizer. There is no narration, rather the scenes feature candid conversation and interviews that serve more as a tribute to Moog than a documentary.

The film was shot on location in Hollywood, New York, Tokyo, and Asheville, North Carolina where Moog's company is based. Additional concert performances were filmed in London and San Francisco.

The film's 2004 release was designed to coincide with the fiftieth anniversary of Moog Music, Robert Moog's company that was founded as R.A. Moog Co. in 1954.

MOOG is an astronomical software package. It is an example of Fortran code that performs a variety of spectral line analysis and spectrum synthesis tasks under the assumption of local thermodynamic equilibrium. Moog uses a model photosphere together with a list of atomic or molecular transitions to generate an emergent spectrum by solving the equation of radiative transfer.

The typical use of MOOG is to assist in the determination of the chemical composition of a star, e.g. Sneden (1973). This paper contains also the description of the first version of the code and has been cited about 240 times as of 2008-04-24 by publications in international journals studying the abundances of chemical elements in stars.

The software package has been developed and is maintained by Christopher Sneden, University of Texas at Austin. The current supported version of the code was released in August 2010 and is described in the MOOG User's Guide (see references below). Moog is written in FORTRAN 77.
