The cover shows an image of the Sun obtained with the Yohkoh Soft X-ray Telescope on 11 November 1991 using the thin Al filter. The intensity range of this image varies by over 100,000 as represented by the black-red-white color scheme. Solar North is up and East is to the left. The brightest areas are solar active regions where sunspots would be seen in visible light; the darkest regions are coronal holes where the gas density is extremely low and from which the solar wind emerges.

The Yohkoh Analysis Guide is intended as an introduction and quick reference to the Yohkoh software, databases and instruments. This document describes the organization of the software, format of the data, instrument characteristics, and a list of the most commonly used programs.
Version 1 of this guide was compiled from information provided by a small number of people, starting from earlier guides by Keith Strong and Alan McAllister.
Version 2 of this guide was compiled from contributions provided from each Yohkoh instrument team and from Co-I's in Japan, the U.K., and the U.S. The number of individuals is too large to list here, but we are thankful for each contribution and suggestion. The LPARL team would also like to thank Prof. Yoshiaki Ogawara, the Yohkoh Project Manager, for his kind encouragement during the compilation of this guide. We are thankful to Drs. Loren Acton, George Doschek, James Klimchuk, and John Mariska who reviewed the final version and made many helpful comments.
As noted above, this document was compiled from a large number of sources. In the case of software, it was not always possible to verify the correctness of the information contained here. We would welcome any comments or corrections which can be sent to the E-mail address given below. Specific questions or comments will be re-directed to the appropriate individuals as necessary.
The Yohkoh team plans to make future software and documentation updates. If you would like to register to receive notification of significant software or instrument calibration updates, please send your name, postal address, and E-mail address to the E-mail address shown below.
