Query: An Efficient Technique for making maps from Observations of the Cosmic
  Microwave Background Radiation   We describe a new technique for turning scans of the microwave sky into
intensity maps. The technique is based on a Fourier series analysis and is
inspired by the lock-in deconvolution used in experiments which typically sweep
the sky continuously. We test the technique on computer generated microwave
skies and compare it to the more standard map making technique based on linear
algebra. We find that our technique is much faster than the usual technique
and, in addition, does not suffer from the problem of memory limitations.
Lastly we demonstrate that the technique works under real experimental
conditions using observations of the moon.
