The InSight IFG (InSight Fluxgate Magnetometer) new calibration bundle replaces the
previous InSight IFG archive. All of the IFG data files have been updated and a new
data collection has been added. There are no changes to any of the data file 
structures so there is no need for users to update any codes that are used to 
display or analyze the data. The only changes to the raw data are in the values
of the model temperature and solar array current columns - IFG columns are 
unchanged. The magnetic field values have changed in the partially processed and
calibrated data files but the changes are generally small. Users should refer
to the InSight_IFG_Data_Udated_Calibration_Description and the Insight_IFG_SIS
documents for the details of the new data processing. 

Note: There were no changes to any of the data products in the data-sc-engineering
collection so those data are not repeated here. Users will find those data in
the original archive bundle urn:nasa:pds:insight-ifg-mars.

Note: These files have completed PDS peer review and many changes have been made
to the review products. However, these are mostly limited to updates in the meta-data
and documents.

The InSight IFG (InSight Fluxgate Magnetometer) new calibration bundle contains several 
collections, each of which is briefly described below:

document: Documents that should be considered required reading
          for this bundle.
      Insight_IFG_SIS - This document describes the archive 
          contents and structure, from science objectives, to file naming
          conventions, to what's stored in byte 78 of file XXX.tab
      InSight_IFG_Data_Calibration - This document describes processing pipelines
          that produced the original (v06) data products and the new (v07)
          data products. The ground data calibration and the types data 
          artifacts and their removal has not changed so users are referred
          to the InSight_IFG_Data_Calibration_Description document in the
          urn:nasa:pds:insight-ifg-mars:document collection for that 
          information.
       InSight_IFG_Data_Uncorrected_Artifacts  - This is a new document
          that describes several types of data artifacts and our failed
          attempts to remove them and why we failed. This document may be 
          useful to users who would like to improve the artifact removal
          for a small set of files for a particular study.                
       SA_Current_Fits - A text file that gives the time varying 
          polynomial coefficients that describe the solar array current 
          corrections applied to the IFG data.
       TemperatureFits - A text file that gives the time varying (one set 
          per release) polynomial coefficients that describe the temperature 
          corrections applied to the IFG data. 
       destep.txt - Psuedo-code that was used to remove long duration
          compound steps in the raw to partially processed data processing
          pipeline software.                   
       ReleaseNotes - A text files that describes the various 
          InSight data releases.

browse:   A collection of PNG plots of the data, one plot per calibrated 
          data file.
          
calib:   A collection of files (one per release) that contain the 
          corrections to the IFG data (delta-B's) that have been applied
          to the data, and the model and actual temperature and current
          values used to compute those corrections.
                   
data-ifg-raw: This collection contains the raw IFG magnetic field vectors
          and some of the ancillary data parameters that are required for
          data calibration and processing. Data are stored as ASCII tables 
          with column headers in line 1.
      
data-ifg-partially-processed: A collection of partially processed data. These
          data have been converted to units of nanoTesla and have had diurnal
          variations that are correlated with the spacecraft systems removed.
          Data are provided in IFG instrument and spacecraft coordinates. 
          Data are stored as ASCII tables with column headers in line 1.
          
data-ifg-calibrated: A collection of calibrated data files that are provided
          in spacecraft and geophysical (north, east, down) coordinates. Any
          artifact identification and removal that can be done at the time
          of a given InSight data release has been applied to these data. In
          addition, these files contain a data quality flag that tells the user
          what (if any) corrections have been applied to the data and which 
          artifact types remain present. Data are stored as ASCII tables 
          with column headers in line 1.
         
data-ifg-calibrated-mav-20Hz: A collection of calibrated 20Hz data files  
          acquired during flyovers of the MAVEN spacecraft. These files have
          had additional hand data processing to remove some of the 
          spacecraft artifacts from the data files. Hovever, not all files
          could be corrected and 24 of 95 still have significant artifacts.
