The three files have my corrections. The text below describes them. One is 
a revised ref.cat. One has revised .lbl files for the smallest raw data set. 
The last has revised .lbl files for the smallest processed data set. 
I think you'll find them much easier to read, and smaller.

Many .cat files have an erroneous First two lines of
/usr/bin/unix2dos  
/usr/bin/dos2unix 

document/soc_inst_icd.lbl
The first value must be ASCII, BINARY, or EBCDIC, so perhaps change
  INTERCHANGE_FORMAT         = HTML
  DOCUMENT_FORMAT            = TEXT
to
  INTERCHANGE_FORMAT         = ASCII
  DOCUMENT_FORMAT            = HTML

index/index.lbl
Line 157: BYTES = 21 should be 19. All subsequent START_BYTEs are 2 off.

catalog/ref.cat
Many small fixes, 1 medium fix: STERNETAL2007 already exists in the PDS
Catalog as STERNETAL2008.  Attached.

data/.../*lbl
DATA_SET_ID: not only do the version numbers differ from the dataset.cats,
but sometimes other parts don't match, e.g. CRUISE vs. CRUISE1
label:   NH-X-SDC-2-CRUISE-V2.0
catalog: NH-X-SDC-2-CRUISE1-V1.0

nh-*-3-*/data/.../*lbl
All these labels define the same table, EXTENSION_CHARGE_DATA_TABLE.
To reduce redundancy and improve reliability, I suggest:
- replacing in every label the definition of that table with a PDS3
pointer, which behaves like C's #include.
- creating extension_change_data_table.fmt that defines the table
The attached file has the suggested changes for one dataset.
  nh-j-sdc-3-jupiter-v3.0a.tar.gz
I could change the other two datasets if desired.

nh-*-2-*/.../*lbl
All these labels define some combination of the same 6 tables. I suggest:
- replacing the definitions of each table with a PDS3 pointer, which
behaves like C's #include.
- creating six .fmt files that define the tables
The attached file has the suggested changes for one dataset.
  nh-j-sdc-2-jupiter.v3.0a.tar.gz
I could change the other two datasets if desired.

soc_inst_icd.htm section 13.2.1
"There  are  five tables in the raw file". There are actually 6.
DATA looks good
HOUSEKEEPING_SDC: 2 and 3 are each actually 4 columns, so you could write:
  2-5) PanTemp A-D 
  6-9) BoxTemp 1-4
HOUSEKEEPING_0X004: this lists 4 columns. There are actually 37.
HOUSEKEEPING_0X00D: this lists 3 columns. There are actually 8.
HOUSEKEEPING_0X00A: this lists 3 columns. There are actually 5.
THRUSTERS: this lists 2 columns. There are actually 28.

soc_inst_icd.htm section 13.4.4
"The two tables in the calibrated FITS file are":
both this document and the .lbl have only 1 table.
