ACE/MAG Release Notes: The following are cummulative release notes for the ACE Magnetic Field Instrument (MAG) Level-2 datasets with 1-sec resolution. As new datasets are released or old datasets are processed, this file will be updated. While MAG uses a badpoint fill value of -999.9, there are occasional minor frames of data with values (0,0,0). The source of this has never been determined and they can be found in the 1-s data. Data where all 3 components of the IMF are "0" should be treated as bad. Note: The ACE spin period is 12 seconds. Consequently, a spin tone can be seen at 1/12 = 0.083 Hz, the amplitude of which is a measure of the inaccuracy of the instrument zeroes. A small spin tone is commonly observed. -------------------------------------------------------------------------- March 13, 2007 Release of DOY 3 of 2007 -- DOY 29 of 2007, 1-sec data for MAG. This is a new data product that will be made available from here out. Every effort will be made to provide the same data product for times already delivered in the ASC catalog. Delivery of earlier times will be made as reprocessing is possible. -------------------------------------------------------------------------- April 24, 2007 Release of DOY 30 of 2007 -- DOY 56 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- April 27, 2007 Release of DOY 57 of 2007 -- DOY 83 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- May 16, 2007 Working backward in time: Release of DOY 160 of 2006 -- DOY 2 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- June 1, 2007 Working backward in time: Release of DOY 44 of 2006 -- DOY 159 of 2006, 1-sec data for MAG. -------------------------------------------------------------------------- June 12, 2007 Working backward in time: Release of DOY 312 of 2005 -- DOY 43 of 2006, 1-sec data for MAG. -------------------------------------------------------------------------- August 20, 2007 Working backward in time: Release of DOY 160 of 2005 -- DOY 311 of 2005, 1-sec data for MAG. -------------------------------------------------------------------------- August 21, 2007 Working backward in time: Release of DOY 1 of 2005 -- DOY 159 of 2005, 1-sec data for MAG. -------------------------------------------------------------------------- October 1, 2007 Working backward in time: Release of DOY 44 of 2004 -- DOY 366 of 2004, 1-sec data for MAG. -------------------------------------------------------------------------- October 2, 2007 Working backward in time: Release of DOY 174 of 2003 -- DOY 44 of 2004, 1-sec data for MAG. -------------------------------------------------------------------------- October 3, 2007 Working backward in time: Release of DOY 38 of 2003 -- DOY 173 of 2003, 1-sec data for MAG. -------------------------------------------------------------------------- October 4, 2007 Working backward in time: Release of DOY 111 of 2002 -- DOY 37 of 2003, 1-sec data for MAG. -------------------------------------------------------------------------- October 8, 2007 Working backward in time: Release of DOY 55 of 2001 -- DOY 110 of 2002, 1-sec data for MAG. -------------------------------------------------------------------------- October 9, 2007 Working backward in time: Release of DOY 58 of 2000 -- DOY 54 of 2001, 1-sec data for MAG. -------------------------------------------------------------------------- November 7, 2007 Working forward in time: Release of DOY 84 of 2007 -- DOY 137 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- November 12, 2007 Working forward in time: Release of DOY 138 of 2007 -- DOY 191 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- November 13, 2007 Working forward in time: Release of DOY 192 of 2007 -- DOY 218 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- November 14, 2007 Working forward in time: Release of DOY 219 of 2007 -- DOY 245 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- November 21, 2007 Working forward in time: Release of DOY 246 of 2007 -- DOY 272 of 2007, 1-sec data for MAG. -------------------------------------------------------------------------- January 23, 2008 Working backward in time: Release of DOY 001 of 1999 -- DOY 057 of 2000, 1-sec data for MAG.
