Cal Highway pix from SRI
4 images are 512x512x8 bits.
SRI1 and SRI3 form a stereo pair with 70% overlap. Wide field,
SRI1 is upper, SRI3 is lower (stereo axis is vertical).
Subject includes straight section of divided highway through
uninhabited area. Access roads lead left and right from highway,
a water tank and dam(?) are on the left.
SRI2 and SRI4 are higher resolution windows (linear factor of 3)
taken from overlap area of previous pair. Stereo overlap is low,
about 10%. Some vehicles visible on the highway.

Explanations
Header Format Evolution: The header format
version number defines what the rest of the header rcord
contains and how it is to be interpreted.
For version 1: Th pixel data format is defined by ipsb, ipib, ipob, idt, and imsk.
The stored pixel values are not packed, ie, ther is one pixel per word
always. Within the word, the pixel value can or will be shifted
right or left when displaying and/or keeping. The subroutine ALTER
is used for shifting and/or masking; if neither operation is wanted,
the data is ready in the same buffer and no time is wasted moving and preparing
data. For displaying, the "and" mask IMSK is applied--after any shifting
is finished to remove undesired bits in the word.
An imsk value of 0 causes the masking operation to be avoided; it is logically
equivalent to a value of -1.

ipib=8 ipob=4
ipsb=16
For any data movement operation, a default signed shift is automatically
computed and undertaken unless the user explicitly specifies an alternate
value to be used. The default shift amount--given by the equation
below--is designed so that alignment occurs with respect to the highest-order
information bit. Scanner core pixel data format is assumed to be ipsb=16,
ipib=9, and ipob=8. ishift=(ipib+ipob)new-(ipib+ipob)old.
Note that ipps and ipus are not utilized for header format version 1.

I have transferred the tape program to TAPE.SAI[1,PDQ] for your reference.
I have transferred the file to AI Lab file AI1.PIC[1,PDQ].

Lynn Murcer, Structural Biology, will have a Perkin-Elmer digitizer soon.
They are said to have an Optronics digitizer now.
∂01-Feb-80 1456 SL Struct Bio Densitometer
Tom, I called Lynn Mercer, Struct. Bio., re Perkin Elmer. She is not
conversant with the device. A $90k P&E densitometer has been ordered
for Nigel Undwin, presently NRC, Cambridge, who is to assume fac. posit.
in Struct Bio this June. Mercer is sending me copy of specs. Perhaps
nothing more to be done until Undwin arrives. To be connected to PDP-11,
and ultiimately to "a central computer" --- SUMEX? - Sid

Custom Color Laboratory will make an 8x8 transparency for $15.
Color Tech Corp. will make a 4x5 negative for $7 and an 8x10
transparency for $25. (In which case they make the 4x5 neg anyway.)
I cannot find a reasonable xxx for "International xxx" with a

calculation of resolution of that series
6" focal length, 1500 ft altitude
altitude/focal length = field of view / image size
field of view at 1500 ft is 9"*1500/6"=2.7*10↑4"
resolution is approx 100 lines/mm * 225 mm = 2.25*10↑4 lines
resolution per line is 1.2" per pixel on ground
