RECORD  SAVE_TELEMETRY_TYPE

!
!   RECORD INFORMATION
!
!------------------------------------------------------------------------------
 
 
DESCRIPTION       "This relation is used to identify the engineering telemetry
                   received from CCS that must be sent to the engineering team
                   in save format. Each type of save dataset is identified by
                   the field save_type. Certain telemetry items are passed on
                   in raw form and the raw_flag is used to identify these
                   items. The instrument save files contain the short mnemonic
                   which is not in the FOF data sent from CCS. "

!------------------------------------------------------------------------------

    FIELD  save_type
        TYPE            C6
        DESCRIPTION     "The name of the save data. ENG is for standard save
                         data. BREATH is for breathing temperatures."

    END_FIELD

    FIELD  ccs_number
        TYPE            I4
        DESCRIPTION     "A positive value less than 64K defined by CCS for
                         every unique telemetry item in the engineering 
                         warehouse. It is the Numeric ID described in the
                         definition of FOF elements (see Appendix A of 
                         HST-ICD-T2). "
    END_FIELD
	
    FIELD  short_mnemonic
        TYPE            C4
        DESCRIPTION     "It is always of the form of an uppercase character
                         and a three digit number. The first character always
                         matches the first character of the CCS mnemonic. 
                         Usually this mnemonic is the same as that used in 
                         shuttle software (called the MS_ID). "

    END_FIELD

    FIELD  raw_flag
        TYPE            C1
        DESCRIPTION     "Y -- only use raw value, N -- use engineering value."
