This directory contains zip compressed ASCII data files of 16-second-averaged ACE Magnetometer browse data, in RTN and GSE coordinate systems. ACE browse data are designed for monitoring large scale particle and field behavior and for selecting interesting time periods. The data are automatically generated from the spacecraft data stream using simple algorithms provided by the instrument investigators. They are not routinely checked for accuracy and are subject to revision. Use these data at your own risk, and consult with the appropriate instrument investigators about citing it. To find out more about the purpose and limitations of the browse data, and for information about how to obtain verified data, see the ACE Science Center web pages, at http://www.srl.caltech.edu/ACE/ASC See header info at beginning of each file for details of the data format.
