This data bundle contains magnetic field KT17 model residuals (DELTA_B), which represent 
the difference between the magnetic field observed by the MESSENGER 
Magnetometer (MAG) and the modeled magnetic field computed from the Korth et 
al. [2017] magnetospheric magnetic field model. This bundle contains several 
collections, each of which is briefly described below:

document: Documents that should be considered required reading materials 
          for this bundle.
      DELTA_B_RDR_SIS - This document describes the archive contents and 
           structure. This includes the generation, validation, and storage of 
	   the Reduced Data Record (RDR) data products, including the file 
	   naming and format conventions.
       ReleaseNotes - A text files that describes the various DELTA_B RDR data 
           product releases.
      
data-sci-mbf: A collection of DELTA_B RDR data products in the Mercury Body 
          Fixed (MBF) coordinate system. Data are stored as ASCII tables.

data-sci-mso: A collection of DELTA_B RDR data products in the Mercury Solar 
          Orbital (MSO) coordinate system. Data are stored as ASCII tables.
          
The research for and preparation of this bundle was funded by NASA’s Planetary Data Archiving, Restoration, and Tools (PDART) 
program under grant NNX16AJ01G issued to Dr. Haje Korth (Principal Investigator) at the Johns Hopkins Applied Physics Laboratory.
