The following constitutes a pre-Peer Review validation of the Deep Space
1 (DS-1) Ion Propulsion System Diagnsotic Subsystem (IDS) volume
(DSIDS_0001), presenting data obtained during the comet Borrelly
Encounter on Sept 22, 2001. Measurements from the IDS were
reprogrammed in flight to collect plasma wave spectra and electric field
pulses indicative of the cometary environment, i.e., dust impacts.
This
is being treated as an SBN instrument, even though the impacts are
inferred from plasma data.

Root Directory
--------------
voldesc.cat:
- The files DS1HOST.CAT, DS1MSN.CAT are pointed to, while the actual
filenames are INSTHOST.CAT & MISSION.CAT. Please
resolve.
- MEDIUM_TYPE = "CDR". The valid choices are:
"CD-ROM",
"CD-WO",
"DVD-R",
"DVD-ROM",
"ELECTRONIC"
Pick the relevant medium.
- VOLUME_FORMAT = ISO-9660-2
Currently, the value is ISO-9660. Please discuss the need to
create
this new value.
- Misspelled words in file ./aareadme.txt
The word Diagnsotic is misspelled on line 10
The word Proecssing is misspelled on line 18
Catalog Directory
-----------------
ids_inst.cat:
- On line 162, there is an ASCII 181 character ('mu-T' unit),
designating micro-Teslas. Please change to 'micro-T' or
'micro-Teslas'.
There is also an ASCII 194 character, which looks like an 'A
hat'. I
don't know what this is, or if it even belongs here. Please
check.
- The word elctrostatic is misspelled on line 41
The word extendes is misspelled on line 75
The word Redonond is misspelled on line 77
ids_ds.cat:
The word spectroometer is misspelled on line 16
The word Millenium is misspelled on line 22
mission.cat:
- Has TABs on line 244.
The word minature is misspelled on line 183
I am unfamiliar with the word closesiptic ion line 194
The word Millenoum is misspelled on line 232
The word SEPpropelled is misspelled on line 265 (needs
hyphen?)
Document Directory
------------------
ids_integrated_report.lbl:
- DOCUMENT_FORMAT = "JPEG" --> "JPG" (extant Std
Val)
- ENCODING_TYPE = "CCITT/3"
CCITT/3 is a compression format specifically designed for black
and
white images such as faxes, scanned pages, etc. Some of
these figures
are in color, and don't appear to be scanned. Please verify
that the
CCITT/3 compression format is actually used in these JPEGs.
- The word highvelocity is misspelled on line 62
- The word chargeexchange may be misspelled on lines 241 475 478 1165

- The word massdeposition may be misspelled on line 723
- The word extendes is misspelled on line 875
- The word velocitydependent is misspelled on line 1053
- The word ofsight is misspelled on lines 1328 1539 1543
- The word thuster is misspelled on line 1515

- The word ionengine is misspelled on line 2084
ids_integrated_report.txt:
- On line 1504, there is an ASCII 176 character (degree sign).
Please
change to 'deg.'.
- On line 2371, there is an ASCII 181 character ('mu-T' unit),
designating micro-Teslas. Please change to 'micro-T' or
'micro-Teslas'.

pws_call_approach_c.lbl:
- DOCUMENT_FORMAT = JPEG --> change to JPG (extant Std

- See comment above on ENCODING_TYPE
Index Directory
---------------
It is noted that, per standard SBN practice, the index table contains
references to the data files only, and not label files.
index.lbl:
- There is a missing quote at the end of the PRODUCT_NAME line.
- The first COLUMN's START_BYTES field is misspelled as START_TYPE, and
it was probably intended to be 2, instead of 1.
index.tab:
- The last two lines of this index table have the target
"19P/Borrelly
(1904 Y2)" in mixed case. Please change to
U/C.
Data Directory
--------------
In all *.lbl files:
- PRODUCT_NAME = "DS1IDS: SB0 encounter data" should be all
caps, since
it's in a _NAME field.
In sb006.lbl:
- DATA_SET_ID = "DS1-C-IDSP-3-RDR-BORRELLY-V1.0", please
remove the 'P'.
^
- PRODUCT_NAME = "DS1IDSPL: SB0 encounter data" should be
"DS1IDS: SB0
ENCOUNTER DATA"
- Is there a reason the 'plasma' designation is included in this
one file?
In psb1_01.lbl & psr1_01.lbl:
- TARGET_NAME = "19P/Borrelly (1904 Y2)" --> change to
uppercase
