PROGRESS DURING TIIE PERIOD
Work has proceeded on the running of actual data through the
Tape Translate program and through the ensemble averaging
STATINTL
program. The ensemble averaging program performs satisfactorily;
program documentation is nearly complete for the ensemble averaging
program and will be sent to the customer with a Fortran listing and
example program output.
Tapes 00546 and 00547 have.: been decoded and run through the
ensemble averaging program. These tapes contained the analytical
micro-step wedges for SO-121, SO-151, 8443, SO-155 and 8442 scanned
with a 1 x 80 micron slit. The resulting step wedge averages were
plotted with minor density as a function of major density for each
wedge and the slopes of the resulting linear relationships were
entered in the absorption coefficient matrix for SO-121, SO-151 and
8443. The inverse of the three resulting matrices (one each for
SO-151, SO-121, and 8442) were created, yielding the conversion
matrices for generating analytical filter microdensities from in-
tegral filter microdensities.
Examination of tapes 00493 and 00384 on which the desaturated
wedges for SO-121 and SO-151 are recorded were examined. It `TFATINTL
found that one trace, RO Si, was missing from each film set. The
omission was found to be an error on the part of
since the written instructions told the operator to trace wedge RO H
instead of RO Si (there is no wedge RO H). Instructions were given
to trace wedge RO Si on SO-151 and SO-121 each on separate tapes and
send them to These tapes have not been received as
yet.
An attempt to read tapes 00493 and 00383 (the SO-121 and 8443
desaturated wedges) indicated tape errors existed. No tape errors
have been detected on tape 00384 containing the SO-151 desaturated
wedges.

A call to the customer's facility yielded the information that
they knew the problem existed, i,ut a satisfactory tape dump could not
be generated to diagnose the problem. Examination of a tare dump
STATINTLgenerated a-t showed that the customer's digitizer
was occasionally inserting extra characters in the middle of a
trichromatic density word. This insertion occurred before the blue
density, between the blue and green or green and red densities or
