3. PERFORMANCE SUMMARY
THE PET JUDGED THE QUALITY OF MISSION 1046-1 AS GOOD, AND CO
ABLE TO THE BETTER J-1 MISSIONS. PORTIONS OF 1046-1 WERE COMPARIBJ-E
TO THE BEST PHOTOGRAPHY EVER PRODUCED BY A J-1 CAMERA. THE PHOT - 25X1._;
INTERPRETERS RATED 10/46-1 AS FAIR TO GOOD AND 1046-2 AS FAIR TO CMX THERE WAS A PROGRESSIVELY WORSENING ANOMALY ON THE ENTIRE NISSI
THAT PRODUCED VARYING IMAGE QUALITY ACROSS THE WEB. ON 1ki46-2 T S
QUALITY 'VARIED FROM GENERALLY :GOOD ON THE OUT60ARU SIDE TO GENNE RALLY
POOR ON THE INBOARD SIDE. THE ANOMALY APPEARS TO BE DUE TO SIGNIFICAvANCE CY
EMULSION BUILD-UP ON THE SCAN HEAD ROLLERS AND IS DISCUSSED IN MORE X
T
WITH TEXT
DETAIL IN LATER SECTIONS IN THIS REPORT. WEATHER CONDITIONS WERE
GENERALLY FAVORABLE, WITH A HIGH PERCENTAGE OF CLOUD AND HAZE FREE F._
ACQUISITIONS. THE INCIDENCE OF SMEAR AS REPORTED IN PARA D (1) OF B.
WAS NOT VERIFIED BY THE PET. THE POOR IMAGERY CAUSED BY THE ANOMALY
WAS OUT OF FOCUS AND NOT SMEARED.
4. ANOMALIES
A. ANOMALY: IMAGERY WAS OUT OF FOCUS ON THE BINARY BLOCK SIDE.
IMAGERY IMPROVED IN QUALITY AND FOCUS ACROSS THE FILM WIDTH.
CAUSE: APPARENT CAUSE OF THIS DISCREPANCY WAS DUE TO EMULSION
BUILD-UP ON SCAN HEAD ROLLERS EFFECTING THE FOCUS.

ACTION: SEE SECTION 5 BELOW
B. ANOMALY: LIGHT LEAKS OF DIFFERING SEVERITY OCCURRED ON THE
FOLLOWING FRAMES OF MOST PASSES. THE AFT CAMERA, LAST FRAME, FIRST,
SECOND, THIRD, FOURTH, AND SIXTH FROM LAST, THE FORWARD CAMERA LAST,
FIRST, AND FIFTH FROM LAST.
CAUSE: TWO DIFFERENT SOURCES OF LIGHT LEAKS CAUSED THE

FOGGING; ONE WAS THE AREA AROUND THE DRUM AND THE OTHER IN THE
VICINITY OF THE INTERMEDIATE ROLLER ASSEMBLY. THE FOGGING NEAR THE
INTERMEDIATE ROLLER ASSEMBLY IS ESPECIALLY SEVERE. WHEN THERE IS A
LONG SET PERIOD BETWEEN CAMERA OPERATES.
ACTION: IN ORDER TO ALLOW FOR THE INCREASED SPEED OF SO-230,
INCREASE THE DURATION AND/OR INTENSITY OF THE LIGHT LEAK CHECK.
(MONITOR:
C. ANOMALY: A BREAKDOWN OF THE FORWARD LOOKING INSTRUMENT
FREQUENCY MARKER SPACING PRODUCED WHAT IS CONSIDERED TO BE AN
ABNORMAL SCAN VELOCITY SIGNATURE WHILE THE AFT LOOKING INSTRUMENT
PRODUCED A NORMAL SIGNATURE. .THE ABNORMAL TRACE INDICATED AN
INCREASED SCAN VELOCITY ERRQR OF APPROX TEN PERCENT AS COMPARED TO
AN APPROX EIGHT PERCENT ERROR NORM. ANOTHER ABNORMALITY TO THE TRACE
WAS A DOUBLE PEAK ON THE FASTER VELOCITY ERROR POSITION OF THE NORMAL

CURVE. OTHER SIGNATURE CHARACTERISTICS APPEARED NORMAL. A SIGNATURE
OF A FORWARD INSTRUMENT FRAME TIME TRACK WAS MADE OF A SAMPLE FRAME
FROM THE HIVOS TEST AT WITH A RESULTING SIMILAR SIGNATURE.
ACTION: THIS ANOMALY APPEARED TO BE A NORMAL SIGNATURE FOR
THIS INSTRUMENT AND DID NGT CONTRIBUTE TO THE IMAGE DEGRADATION. NO
ACTION INDICATED.
6. EVALUATION OF SO-230 FILM:
TYPE SO-230 FILM WAS USED IN MISSION 1046. THE USE OF SO-230
PERMITTED A REDUCTION IN THE CAMERA SLIT WIDTHS BECAUSE OF THE
INCREASE IN PHOTOGRAPHIC SPEED OF THIS FILM WHEN COMPARED TO TYPE
3404 FILM. SLIT WIDTHS OF= O. 110 AND 0. 140 INCH USED ON THIS MISSION
PROVIDED A 2/3 STOP (0.20 LOG E) EXPOSURE REDUCTION FROM THE
NOMINAL 3404 SLITS. THE RESOLVING POWER OF SO-230 COMPARES TO THAT
OF TYPE 3404. THE GRANULARITY OF SO-230 IS SLIGHTLY GREATER THAN
3404. THE COMBINATION OF FASTER FILM SPEED WITH ONLY SLIGHTLY
GREATER GRAIN SIZE MAKES TYPE SO-230 FILM A DESIRABLE FILM FOR BOTH
J-1 AND J-3 USE.
EXCELLENT SYSTEM PERFORMANCE WAS ACHIEVED (TO WIT, MIP 90 ON
1046-1); HOWEVER, SYSTEM PERFORMANCE WAS NOT MAINTAINED THROUGHOUT
THE MISSION. OBSERVATIONS RELATIVE TO THE FILM WHICH MAY HAVE SOME
PAGE 5 3 64 0 T 0 P S E C R E T
BEARINU UN E ORMANCE ARE AS FOLLOWS:
A. PRIOR TO PROCESSING, THE SO-230 FILM WAS OBSERVED TO HAVE
A GREATER THAN NORMAL CURL.
B. EMULSION DUST WAS OBSERVED ON THE HUB ROLLER OF THE
1046-2 (B) SRV. (SEE REF THE DUST FORMED TWO CIRCUM-
FERENTIAL BANDS AROUND T rr wiTH A SPACING SIMILAR TO THE
MARKINGS INTRODUCED ONTO THE FILM BY THE CAMERA RAILS.
C. BASE PLUS FOG INCREASES OF 0.04 TO 0.06 DENSITY WERE
OBSERVED ON PORTIONS OF THE 1046-1 SEGMENT IN AREAS WHERE THE FILM
WAS AT REST FOR PROLONGED PERIODS OF TIME. MINUS DENSITY MARKS
PERPENDICULAR TO THE LONG FILM DIMENSION WERE OBSERVED IN THE PLUS
DENSITY REGION. THE REDUCTION IN DENSITY IS OF THE SAME MAGNITUDE
AS THE DENSITY INCREASE AND IS BELIEVED TO BE ASSOCIATED WITH THOSE
FILM AREAS WHICH WERE IN CONTACT WITH ROLLERS. AFTER PASS 95 THE

MARKS ARE BARELY DETECTABLE AND CANNOT SE IDENTIFIED DENSITOMETRI-
CALLY.
D. SOME INCREASE IN GRAININESS WAS OBSERVED ON THIS MISSION.
THIS MAY BE DUE IN PART TO'-THE APPARENT OVEREXPOSURE OBSERVED ON
THIS MISSION. THE MISSION RECEIVED A SIGNIFICANT PROPORTION OF PRIMARY
PROCESSING (APPROX 34 PERCENT) AND AN UNUSUALLY LOW AMOUNT OF FULL
PROCESSING (APPROX 19 PERCENT). ANALYSIS OF THE ABOVE FILM
OBSERVATIONS ARE:
A..--CURL: OBSERVATIONS MADE DURING A SPECIAL POSTFLIGHT TEST IN
TH NIGH VACUUM CHAMBER INDICATE THAT THE FILM FLATNESS OF 25X1
3404 AND S0-230 FILM APPEARED SIMILAR. ANALYSIS OF CURL CHARACTER-
ISTICS HAVE BEEN INITIATED AT BUT HAS NOT BEEN COMPLETED. 25X1
(MONITOR: u 25X1
B. EMULSION DUST: TESTS OF THE PHYSICAL HARDNESS OF SO-230
COMPARED TO TYPE 3404 FILM ATF__7INDICATE THAT THERE IS NO 25X1
SIGNIFICANT DIFFERENCE BETWEEN THESE 0 FILMS. OBSERVATIONS MADE
ON A SPECIAL POSTFLIGHT TEST IN THE HIGH VACUUM CHAMBER 25X1
INDICATED THAT:
(1) EMULSION DUST (FROM RAIL SCRATCHES) WAS GENERATED WHEN
USING BOTH TYPE 3404 AND SO-230 FILM.
(2) EMULSION DUST WAS GENERATED ON BOTH CAMERAS.
PAGE 2 13 64 0 T 0 P S E C R E T
(3) A LARGER AMOUNT OF EMULSION DUST FROM SO-230 FILM WAS
OBSERVED ON BOTH CAMERAS.
(4) THE AMOUNT OF DUST GENERATED BY ONE CAMERA WAS GREATER
ON BOTH FILMS THAN THAT PRODUCED BY THE OTHER.
ACTION:
A. WILL INVESTIGATE THE POTENTIAL OF IMPROVING THE
ABRASION RESISTANCE OF SO-230. (MONITOR:
B. WILL INVESTIGATE POTENTIAL IMPROVEMENTS IN THE
MANUFACTURE AND OR POLISHING OF RAILS FILM CONTACT POINTS
TO MINIMIZE FILM ABRASION. (MONITOR:
C. FOG BUILD-UP: THOUGH NOT DESIRABLE, THE MAGNITUDE OF THIS
DEFECT DOES NOT APPEAR TO SIGNIFICANTLY AFFECT THE INTELLIGENCE
VALUE OF THE MISSION.
D. INCREASE IN GRAININESS:
(1> IS MAKING AN ANALYSIS OF THE
SO-230. THESE FINDINGS WILL BE REPORTED. (MONITOR:
(2) IS MAKING AN ANALYSIS OF THE RELATIVE
DIFFERENCES IN PHOTOGRAPHIC SPEED OF SO-250 AND 3404 FILM WHEN
EXPOSED IN A VACUUM. (MONITOR:
