The Forerunner (MRFFR) instrument Housekeeping data contain information about the state of the instrument. The data are provided in comma separated variable (CSV) text files. The exact contents of this may vary depending on data rate and other factors. See below table for a description of the ancillary data product, which contains these data.

The instrument housekeeping data (engineering data) |
MRFFR instrument Housekeeping data products have the following file names:
FSB_nnnnn_Rtt_XrB_aadooo_Vz.xxx (with one detached PDS label for the two data files and one detached PDS label for the housekeeping product)
where:
F = instrument = Forerunner
S = frequency band = S-band
B = radar mode = Baseline SAR
nnnnn = orbit number in which data acquisition began, numeric range 00001…99999
R = processing level = Raw PDR
tt = file type
PD = Packetized Data Records
HK = Instrument Housekeeping data
X = projection = N/A
r = pixel resolution bin scale in pixels per degree (ppd) and meters/pixel (mpd)
H = 128 ppd, 237 mpd
I = 256 ppd, 118 mpd
B = bit type and scaling = Byte
aa = lunar center latitude to nearest whole degree, numeric range 00…90, XX = N/A or Unknown
d = hemisphere of latitude
N = North latitude
S = South latitude
X = N/A
ooo = lunar center longitude to nearest whole degree, numeric range 000…359
z = product version number, numeric range 1…9
xxx = file extension
DAT = Unformatted binary data (e.g., raw files)
TXT = Unstructured text data (e.g., parameter files)
CSV = Comma Separated Value text files (housekeeping)
In ODE, HK products have the following product IDs:
FSB_NNNNN_RHK_XRB_AADOOO_VZ
Note:
The Packetized Data Records (PDR) that are associated with the PDS3 Data Set ID (CH1-ORB-L-MRFFR-1-PDR-V1.0) were not migrated to PDS4. They are telemetry data in a format that could not be converted to a PDS4-compliant format. Given that PDR data share the same Data Set ID as the housekeeping data in PDS3, they have been cross-referenced in the product details page of the housekeeping data in PDS4. Additionally, a direct download link for the PDR data has been provided.
