The Gamma Ray Spectrometer Experiment Data Record (GRSEDR) GRS Engineering Records (GRSENG) are composed of two data types: engineering and channelized data. Engineering data are time series records for the 68 different engineering readings monitored in the GRS, and the associated timing information. The engineering readings can be taken at several different time intervals, which can be changed depending on spacecraft operation. Times associated with the individual readings can be used to determine the sampling intervals. Channelized data are time series records for the other 26 engineering readings from the spacecraft, and the associated timing values. Some of the channelized readings are only recorded when there is a change in the setting, whereas others are sampled on a regular interval.

Each engineering reading is output to its own file, which are grouped in ODE into a set of products for each date: YYYYMMDD. For each date, there should be (although there may not always be) a product with the engineering data and a product with the channelized data.

In ODE, GRS Engineering data have one of the following product IDs:

B_170K_TEMP_YYYYMMDD

CEB_AD_TEMP_YYYYMMDD

CEB_AGND_SPARE1_YYYYMMDD

CEB_HTR_CNTRL_TEMP_YYYYMMDD

PLUS_5V_ANLG_YYYYMMDD

 

In ODE, GRS Channelized data have one of the following product IDs:

CHAN_GRS_AD_EN_ST_YYYYMMDD

CHAN_GRS_ANDR_ST_YYYYMMDD

CHAN_GRS_ANNEAL_YYYYMMDD

CHAN_GRS_BOOT_ST_YYYYMMDD

CHAN_GRS_CEB_TMP_YYYYMMDD
