MESSENGER: NS Calibrated Data Records

The MESSENGER NS Calibrated Data Records (CDRs) consist of calibrated raw neutron spectra, NS counter data, galactic cosmic ray spectra, engineering data, and gamma-ray burst data. Each CDR is organized as a binary or ASCII table containing observations with a time tag corresponding to a given Earth day, along with a detached ASCII text PDS label file. The files are grouped in directories by Earth year and month.

The NS CDRs are stored along with the NS Derived Data Records (DDRs) on PDS volume MESSNS_2101. Please see below for direct access to the volume.  Only directories pertaining to the CDRs are listed below.  Alternatively, to search the archive for data that meet particular criteria, e.g. time and location, use the Mercury Orbital Data Explorer (ODE).
