MESSENGER PDS3 to PDS4 Migration Status: Complete

For more information about XRS calibrated products, see the Product SIS.

Note: The product SIS was created for PDS3, but it is still applicable to the data after the PDS4 migration.

The MESSENGER XRS calibrated product collection consists of calibrated XRS spectral data. The supernova remnant X-ray source Cassiopeia-A (Cas-A) was periodically used for in-flight calibration due to its relatively high intensity in the XRS energy range. A description of this product type is given in the table below. Code refers to the product type abbreviation used in the file name.

Code	Product Type	Description	Storage Format
CDR	Spectra	This table contains calibrated X-ray spectra and associated instrument parameters such as detector energy calibration, engineering data conversions, and spatial data which will be necessary to convert raw XRS counts to planetary surface compositions.	Binary Table

XRS Calibrated products have the following file names:

xrscdryyyyddd.dat

where:

yyyy = 4-digit year corresponding to the Mercury Elapsed Time (MET) for each product

ddd = 3-digit day of year corresponding to the MET for each product in the EDR
