ASTAT

Measure image statistics

Format

ASTAT opt coord <keywords>


Parameters

opt option type:
 
BOX rectangular outline (default)
CIR circular or ellipitical outline
IRR irregular shaped outline
LIN outline based on line between 2 points
coord coordinate type
 
IC image coordinates (default) All options are designed to run interactivly on the current image frame
EC earth coordinates
  EC station dist surface station location and radius (km) for CIR
  EC lat lon dist latitude/longitude circle and radius (km) for CIR
  EC LAT=lat1 lat2
LON=lon1 lon2
lat/lon pairs for BOX

Keywords

AREA= area number
BAND= spectral band (default= current frame or, 1st band in area)
COLOR= graphics color (default=2)
CUT=
lo hi data range (default=0 10000)
TAIL=
pct tail percentage 0-100 (default=5%)
HIST=
gframe plot a histogram on graphics frame (default=no plot)
LAT=
