>NOTES from digitizing ...
>This file was created by digitizing all 4 paper rolls of 12 khz bathy
>from cruise L4 90SC (Bohannon/Eittreim) using the analog_dig program
>on suna in B-111 by J. Riordan. 10/2/90.

>Roll Start End
> 1 130 1218 - 133 1825
> 2 133 1825 - 138 1231
> 3 138 1233 - 141 0311
> 4 141 0325 - 144 0505
>
>NOTE 1:
>Values from rolls 1 and 2 HAVE been corrected (-) by 20m by a program.
>There were significant differences between the depth value recorded
>by the watchstanders and the digitized depth. This difference is due
>to an offset on the top margin of the record which was measured by
>S. Eittreim to be equivalent to 20m. How ? Record is 2 second sweep (1500m),
>divided by 20 equal sections = 75m per section. The offset from the
>top was measured with 10 point ruler to be 20m.
>
>OTE 2:
>Values from rolls 3 and 4 WERE corrected by 20 meters at the
>time of digitizing to make up for the uneven top & bottom edges of the
>record - per Steve Eittreim.
>Method used in program:
>When entering the bottom depth for each section, 20m was subtracted off the
>bottom range. Example of ranges used: 0-1500 was adjusted to 0 - 1480,
>1500 - 3000 was 1500 -2980, 3000 - 4500 was 3000 - 4480.
