DESCRIP2

For each Level 2 dimension ($i=$1,...,OBJDESC.NDIM2) there must be a single record in this record type. The descriptor records may be in any order, but it is recommended that they be in the order 1 through OBJDESC.NDIM2. This record is considered the authoritative source of information for this dimension. A parallel description can be supplied in the DESCRIP record type. There must be a DESCVAL record for each DESCRIP2 record which specifies 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 = 32

NDEX

I

specifies which Level 2 dimension is being described. Counting begins at 0 or 1 as specified in the TEST.SPECB.IDXSTART field. Note that this index does not refer to an index position of an actual data array but is instead a pointer into the DIMSPEC2.INDEX field. See the discussion in Section 2.3.2

DUPNUM

I

is the number of DESCRIP records for this dimension

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.1.4

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 DIMSPEC2.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
