A2.6 Other Features

 

In the course of developing this program, several features have been added or changed in LANSPECT and other LAN programs as follows:

 

  • The seek capability has been added to read_archive.for.
  • The printing of all times read from the tape on the standard output has been suppressed.
  • The ability to read UAV input has been added for LANSPECT as well.

 

A2.7 Additional Information

 

This is an example to show how the linear and log scaling algorithms work. We start with flux values in eight directions, already normalized if necessary

 

8 flux values: 50 50 20 10 10 10 5 5
sum=160; avg=20        
Divide by avg: 2.5 2.5 1.0 .5 .5 .5 .25 .25
scale=2.0  LINEAR SCALING      
Range limit (0-2): 2.0 2.0 1.0 .5 .5 .5 .25 .25
Divide by : 1.0 1.0 0.5 .25 .25 .25 .125 .125
Color index=240* + 2
