This file contains an accumulation of corrections and notes for the           
CH-1 M3 Level 2 Data Product Archive.  The most recent entries are

   Changed the title of the reference BESSEETAL2012 in REF.CAT.               
                                                                              
2)  06 March 2012:  Added two alternative photometry tables, one for global   
    mode and another for target mode, to the EXTRAS directory (refer to the   
    detached labels for more information):

3)  06 March 2012:  Fixed typos in two labels in the CALIB directory:         
                                                                              
      M3T20111109_RFL_F_ALPHA_HIL.LBL - Corrected typo in DESCRIPTION for     
                                        table column 2.                       
      M3G20111109_RFL_F_ALPHA_HIL.LBL - Corrected typo in DESCRIPTION for     
                                        table column 2 and in PRODUCT_ID.     
                                                                              
4)  April 2011:  Non-standard PDS unit, Astronomical Unit (AU)                
                                                                              
    The keyword element, SOLAR_DISTANCE, contains a value that uses the       
    Astronomical Unit (AU), a non-standard PDS unit, as the unit of           
    measurement.                                                              
                                                                              
    The SOLAR_DISTANCE value is used by the M3 team as a measure of the       
    distance to the Sun to modulate the solar irradiance. The solar flux      
    varies a few percent (as 1/R^2) as the to-Sun distance varies from about  
    0.98 to 1.02 AU during the year.                                          
                                                                              
    The AU, a basic non-SI unit of length for bodies within the solar system, 
    is recognized by the International Astronomical Union (IAU) for use in    
    astronomy and planetary science. The AU is also recognized by the         
    National Institute of Standards and Technology (NIST). For more           
    information see
