2. SYSTEM DESCRIPTION
2.1 PURPOSE
The purpose or the LACSEG processor is to convert the LAC/HRPT data tapes
to Universal formatted data tapes which can be processed by IMDACS.
2.2 USAGE
The LACSEG processor is set up as a batch run. The input to the processor
will be the multi-reel LAC/HRPT tapes and control cards. The output will
be a Universal formatted image tape consisting of the data lines and pixels
requested on the control cards. Both input and output tapes will be 1600 bpi.
The 10 bit input pixel data will be scaled to 3 bit data as follows: For
channels 1 and 2, all pixel values greater than 255 will be reset to 255;
for channels 3 and 4, all pixel values will be divided by 4. No data will
be output for channel 5.

5.1.3 PAPER
A report of any tape processing errors and a count of the number of pixels
on channels 1 and 2 reset to 255 will be printed on the line printer.
Example:
2722003 PIXELS ON CHANNEL 1 WITH VALUES OVER 255. THESE WERE RESET TO 255
2430702 PIXELS ON CHANNEL 2 'WITH VALUES OVER 255. THESE WERE RESET TO 255.

6. SPECIAL INSTRUCTIONS OR RESTRICTIONS
The job normally runs approximately 1-1/2 hours. However, run time will
depend on system loading.
