3. PERFORMANCE SUMMARY
A. THE IMAGE QUALITY OF MISSION 1037-1 AND 1037-2 IS CON-
SISTENTLY GOOD AND COMPARABLE TO MISSION 1035. A PRIMARY REASON

FOR THE HIGH QUALITY OF THE MISSION IS CONSIDERED TO BE 'UNUSUALLY
GOOD ATMOSPHERIC CONDITIONS. ANALYSIS OF CLOUD COVER FROM -INDEX
CAMERA PHOTOGRAPHY SHOWS AN EXCEPTIONALLY HIGH PERCENTAGE OF
CLOUD FREE AREAS (SEE PARA 6 - COMMENTS).
B. VISUAL COMPARISON OF ORIGINAL NEGATIVE AND DUPLICATE
POSITIVE FILMS FROM BOTH SEGMENTS OF THE MISSION INDICATES THAT
THE AFT CAMERA IMAGERY CONTAINS SLIGHTLY GREATER DETAIL THAN
THAT OF THE FORWARD CAMERA. THIS RELATIONSHIP IS CONSISTENT
WITH RESULTS FROM MOST PREVIOUS MISSIONS.
C. NO CORN TARGETS WERE RECORDED ON THIS MISSION.
D. MISSION 1037 IS THE SECOND "J" SYSTEM FLOWN WITH THE
PHOTOGRAMMETRIC CONFIGURATION. DETAILS OF PG PERFORMANCE ARE
DISCUSSED IN PARAGRAPH 5.
4. ANOMALIES
ANOMALIES INCLUDING THOSE REPORTED IN THE "31" MESSAGES (REFS.
A AND B) WERE REVIEWED.
A. BOTH PAN CAMERA FILMS HAD HIGHER THAN NORMAL BASE PLUS
FOG DENSITIES THROUGHOUT THE MISSIONS WITH DENSITIES DURING
MISSION 1037-2 SLIGHTLY HIGHER THAN THOSE IN 1037-1. THE TOTAL
BASE PLUS FOG VALUES AT THE FULL LEVEL OF DEVELOPMENT RANGED
FROM 0.34 TO 0.38, WHILE HEAD AND TAIL SENSITOMETRIC CONTROL
STRIPS SHOWED BASE PLUS FOG DENSITIES OF 0.18 TO 0.20.
CAUSE: ABOUT HALF (0.1 DENSITY) OF THE DISCREPANCY
CAN BE DIRECTLY ATTRIBUTED TO AN INHERENT DIFFERENCE BETWEEN
THE BATCH OF TYPE 3404 FILM USED FOR PROCESS MACHINE CONTROL

AND THE ACTUAL FLIGHT MATERIAL. THIS DIFFERENCE WAS
MEASURED BY PROCESSING SENSITOMETRIC EXPOSURES PREPARED ON
SAMPLES OF FLIGHT MATERIAL REMOVED BEFORE LAUNCH ALONG WITH
CONTROL STRIPS. THERE IS NO APPARENT EXPLANATION FOR THE
REMAINING 0.08 TO 0.10 FOG DENSITY.
ACTION: REVIEW BASE PLUS FOG DENSITIES OF FLIGHT
MATERIAL FROM PREVIOUS MISSIONS TO DETERMINE NEED FOR FURTHER
ACTION.
B. RAIL SCRATCHES FROM BOTH PAN CAMERAS WERE SUBSTANTIALLY
LESS THAN USUAL ON PAST SYSTEMS. THE SLAVE CAMERA. FORMATS HAD
SLIGHTLY RAGGED EDGES DUE TO SCRAPED EMULSION NEAR THE TAKE-UP
END ON THE BINARY RAIL.
CAUSE: THIS SYSTEM WAS FLOWN WITH POLISHED RAILS.
THE REDUCED SCRATCHING IS ATTRIBUTED LARGELY TO THIS FEATURE.
ACTION: THIS ITEM IS INCLUDED TO NOTE THE EFFECTS OF
POLISHED PAN CAMERA RAILS. NO ADDITIONAL ACTION IS INDICATED.
C. LOW DENSITY FOG STREAKS ARE LOCATED JUST INSIDE THE RAIL
EDGES OF FORMATS FROM BOTH PAN CAMERAS. THESE STREAKS ARE
MINOR AND BARELY DETECTABLE IN MOST CASES.
CAUSE: THE FOG STREAKS ARE CAUSED BY RAIL HOLE LIGHTS
REFLECTED OFF THE RAILS. HAS ALREADY MODIFIED THE
SIZE OF RAIL HOLE LAMP APERTURES IN PG EXPOSURE SLITS TO
REDUCE THIS FOGGING.
ACTION: MONITOR TEST RESULTS IN FUTURE SYSTEMS TO
VERIFY CORRECTIVE ACTION.

D. LOW DENSITY LIGHT LEAK AFFECTS SMALL AREAS OF BOTH
PAN CAMERA FILMS AT TIMES OF LONG NON-OPERATE PERIODS.
CAUSE: THERE APPEARS TO BE TWO SOURCES OF LIGHT LEAKAGE,
EACH AFFECTING BOTH PAN CAMERA FILMS. WHILE EXACT LOCATION
OF THE SOURCES HAS NOT BEEN ESTABLISHED, ONE IS THE VICINITY
OF THE SLAVE CAMERA OUTPUT H.O. , AND THE OTHER IN THE VICINITY
OF THE MASTER CAMERA DRUM.
ACTION: SINCE THE FOG PATTERNS (1) DID NOT OCCUR IN
TEST (2) ARE NOT FROM USUAL PROBLEM LOCATIONS, AND (3) ARE
OF VERY MINOR SIGNIFICANCE, THE PET DOES NOT CONSIDER THE
ANOMALY TO WARRANT FURTHER INVESTIGATION.
E. DOUBLE EXPOSURES OCCURRED ON STELLAR AND INDEX FRAMES
253 OF MISSION 1037-1, AND FRAMES 1 AND 397 OF MISSION 1037-2.
CAUSE: THE DOUBLE EXPOSURES OF FRAMES 1 (1037-2) IS
A NORMAL CONDITION OF PHASING THE S/I SEQUENCE OF OPERATIONS
FROM LAUNCH CONDITION. THE DOUBLE EXPOSURES OF FRAMES 253
(1037-1) AND 397 (1037-2) APPEAR TO HAVE BEEN CAUSED BY THE
SWITCH OF S/I PROGRAMMER CONTROL FROM FORWARD TO AFT CAMERA.
IN BOTH CASES, THE FIRST COMMAND THAT THE AFT CAMERA GAVE
WAS A PLATEN COMMAND. THE CONDITION HAS NOT BEEN COMPLETELY
ESTABLISHED BUT IT APPEARS TO BE INHERENT IN THE DESIGN.
ACTION: INVESTIGATE TRADE-OFF OF REDESIGN VS SIG-
NIFICANCE OF THE PROBLEM.
F. CRESCENT SHAPED AREAS OF GROUND IMAGERY ARE VISIBLE
THROUGH THE CORRELATION LAMP HOLES OF BOTH INDEX CAMERAS AT
TIMES WHEN THE CORRELATION LAMP IS OFF. THE CONDITION DflE

NOT AFFECT USE OF CORRELATION LAMP IMAGES.
CAUSE: IMAGED LIGHT BEYOND THE FORMAT AREA ENTERS A
SPACE BETWEEN THE RESEAU PLATE AND THE CORRELATION LIGHT
TUBE. THE CONDITION IS NOT CONSIDERED A FUNCTIONAL HAZARD.
ACTION: NONE INDICATED.
G. GROUPS OF PLUS AND MINUS DENSITY STREAKS AND ASSOCIATED
INDENTATIONS OCCUR ACROSS THE WIDTH OF THE AFT CAMERA FILM OF
MISSION 1237-2. THE STREAKS AND INDENTATIONS WHICH ARE AT
VARIOUS ANGLES TO THE FILM EDGE, APPEARED ON PASSED D84, D166,
D167 AND D168.
CAUSE: UNKNOWN.
ACTION: NONE INDICATED.
H. CHARACTERISTIC ANOMALIES: THERE ARE CERTAIN CHAR-
.ACTERISTIC ANOMALIES WHICH ARE CONSIDERED INHERENT TO THE
OPERATION OF THE CORONA SYSTEM. WHILE THESE ITEMS WARRANT
ATTENTION TO PREVENT FURTHER DEGRADATION IT IS NOT FELT THAT
SPECIFIC ACTION ITEMS SHOULD BE ASSIGNED. A SUMMARY OF THESE
ITEMS AND THE DEGREE OF DEGRADATION IS PRESENTED BELOW.
(1) RAIL SCRATCHES - SEE PARA 4B ABOVE.
(2) DENDRITIC STATIC DISCHARGE ALONG THE EDGE OF BOTH
PAN CAMERA FILMS; IS CONSIDERED NORMAL.
(3) SCRATCHES WITHIN THE FORMATS OF BOTH PAN CAMERAS
CAUSED BY THE SCAN HEAD ROLLERS ARE LESS THAN NORMAL.
(4) INTERMITTENT FINE SCRATCHES GENERALLY PARALLEL
TO THE MAJOR AXIS OF BOTH MAIN FILMS OCCUR TO AN AVERAGE

FILM MARGINS WAS NORMAL.
(6) THE PLUS DENSITY STREAKS REFERRED TO AS "JET-
TISONED FUEL PARTICLES" PERSISTED LONGER IN 1037-1 THAN
NORMAL. THERE WAS ONLY ONE OBSERVED ON THE 1037-2 STELLAR
FILM.
5. PHOWGRANMETR IC DATA RECORDING (PG)
A. THE ANALYSIS OF THE DATA PRESENTATION PECULIAR TO THE
PG PORTION OF 1037-1 AND 1037-2 WAS MADE FROM O.N. MATERIAL AND
WAS COMPARED DIRECTLY WITH INSTRUMENT SAMPLINGS PRODUCED DURING
A/P TESTING AT R-4 DAY. THESE COMMENTS ARE NOT INTENDED TO BE
AN INDICATION OF THE ULTIMATE USABILITY OF THE PG DATA. IN
GENERAL, THE MASTER INSTRUMENT (FWD-LOOKING NO. 198) PRODUCED
BETTER QUALITY RAIL HOLE IMAGES ON THE OUTBOARD (200 PPS) RAIL
THAN DID THE SLAVE INSTRUMENT. THE MASTER INSTRUMENT IMAGES
WERE AT BEST ONLY FAIR, BEING ELONGATED IN THE SCAN DIRECTION.
THE INBOARD RAIL IMAGE QUALITY OF THE MASTER INSTRUMENT WAS
POOR, EXHIBITING CONSIDERABLE INCONSISTENCY IN IMAGE SIZE,
DENSITY, AND GENERAL SHAPE'. THE IMAGES ARE GENERALLY INCOM-
PLETE AND DO NOT EXHIBIT CIRCULARITY, EDGE SHARPNESS OR HIGH
DENSITY. THE SLAVE INSTRUMENT (AFT-LOOKING NO. 199) PRODUCED
OUTBOARD RAIL HOLE IMAGES THAT VARIED FROM GOOD TO POOR IN
ANY ONE FRAME. THE INBOARD RAIL IMAGES WERE GENERALLY SIMILAR
TO THE OUTBOARD EXCEPT SOMEWHAT BETTER IN QUALITY, FROM GOOD
TO FAIR IN ANY ONE FRAME.
B. BLOCKED RAIL HOLES - THE LOSS OF RAIL HOLE IMAGES

DURING MISSION 1037 CORRELATED IN PART TO THE PASSAGE OF
MANUFACTURING SPLICES. THIS CORRELATES WITH MISSION 1035
(REF: 1035 PEIR). COMPARISON TO THE PREVIOUS FRAME IN BOTH
CASES INDICATES THAT NO HOLES WERE LOST DURING INPUT METERING.
HOWEVER, A COMPARISON TO THE FOLLOWING FRAMES SHOW THAT I. ? BOTH
INSTANCES, ALL THE HOLES ON THE OUTBOARD RAIL BETWEEN THE SPLICE
AND THE TAKE-UP END OF THAT RAIL, WHICH WERE PREVIOUSLY CLEAR,
BECAME BLOCKED AS THE SPLICES WERE METERED OUT OF THE RAILS.
C. THE NODAL TRACES ON THE ORIGINAL NEGATIVES ARE SIMILAR
IN APPEARANCE TO THOSE SEEN IN PRE-FLIGHT TESTING WITH TWO
MAJOR EXCEPTIONS:
(1) THE OVERALL DENSITY OF THE TRACES ON BOTH CAMERAS
IS GREATER IN THIS MISSION THAN IN 1035-1 AND 1035-2. THIS
IS DUE IN PART TO THE FACT THAT THE TRACES EXHIBITED HIGHER
DENSITIES DURING PRE-FLIGHT TESTING, AND IN PART TO THE
INCREASE IN BASE PLUS FOG WHICH RESULTED IN HIGHER NODAL
TRACE DENSITIES.
(2) THE DECREASE IN LINE WIDTH TO 25 MICRONS IS A
FUNCTION OF OPERATION UNDER VACUUM CONDITIONS. THERE WAS
NO INSTANCE OF UNDULATING OR MISSING NODAL TRACES DETECTED.
6. COMMENTS
A. THE INDEX CAMERA PHOTOGRAPHY ANALYSIS IS AS FOLLOWS:
1037-1, FRAMES WITH LESS THAN 10 PERCENT CLOUD COVERAGE
143 OR 31 PERCENT.
1037-2, FRAMES WITH LESS THAN 10 PERCENT CLOUD COVERAGE
207 OR 44 PERCENT.

B. ALL MAIN CAMERA 14ATERIAL WAS PROCESSED ON THE TRENTON
EQUIPMENT.
C. THE PHOTO INTERPRETERS INDICATED THAT THE NODAL TRACES
ON SEVERAL OCCASIONS INTERFERED WITH THE ANALYSIS OF TARGETS.
THE TRACES WERE FOUND TO BE DISTURBING DURING THE EVALUATION
OF THE FILM WHILE BEING RAPIDLY SCANNED.
