DESCRIP

For each Level $j$ ($j = 1, 2, 3$) dimension there will be DIMSPEC$j$.DUPNUM DESCRIP records. The descriptor records may be in any order, but it is recommended that they be in order of Level 1: 1 through
[4]DIMSPEC1.DUPNUM, followed by Level 2: 1 through
[4]DIMSPEC2.DUPNUM, followed by Level 3: 1 through
[4]DIMSPEC3.DUPNUM. The information in this record type is considered to be an alternative description of the dimension it parallels. There must be a DESCVAL record for each DESCRIP record, to specify the grid points along that dimension. An optional DESCSUP record may be present if additional information is required.

name

RECTYPE

I

is the record type code = 34

LEVEL

I

is the dimensional level

DEXSORT

I

NDEX

(bits 0-15) is an index that corresponds to the same field in the associated DIMSPEC1, DIMSPEC2, or DIMSPEC3 record. Counting begins at 0 or 1 as specified in TEST.SPECB.IDXSTART. See the discussion in Section 2.3.2

RECSORT

(bits 16-31) is an index that corresponds to the same field in the associated DIMSPEC1, DIMSPEC2, or DIMSPEC3 record. See the discussion in Section 2.3.2

DESSUP

I

is the number of floating-point values in the SVALS field of the following DESCSUP record. If zero, then there is no DESCSUP record for this dimension

DESFMT

I

is the descriptor format code. This code is explained in Section A.1.1

DESTYPE

I

is the quantity code for the physical quantity that the dimension represents. This code is explained in Section A.1.3

UNITS

I

is the units code for the physical quantity that the dimension represents. This code is explained in Section A.1.1

STORG

I

specifies how the values of the descriptor are stored in the DESCVAL record which follows. The possible values are:

0	=	an explicit array of [4]DESCRIP1.GPTNUM, DIMSPEC2.GPTNUM, or DESCRIP3.GPTNUM values
1	=	an implicit specification consisting of a (low-value, interval) pair
2	=	an implicit specification consisting of a (low-value, high-value) pair

DINDEX

I

index serving as an identifier (within a given DEXSORT and LEVEL) of the Descgroup record group begun by this record. Values must be greater than zero. (A value of zero would imply that this is a DESCRIP1, DESCRIP2, or DESCRIP3 record instead of DESCRIP.)
