NAME

lpeaks -- finds local peaks in an image above threshold

USAGE

lpeaks image rpos_tab

DESCRIPTION

LPEAKS scans the SNR map line by line for local peaks above a user-defined threshold. The peaks are written to an output table.

PARAMETERS

image = "" prompt = Input Snrmap Image

Name of the input Snrmap image file to be read.

rpos_tab = "" prompt = Output Rough Positions Table

Name of table file to be written.

(thresh = 2.5) [real]

Threshold above which peaks will be saved.

(display = 2) [int]

Display info to screen. Integer of range 0-5. The higher the number more verbose the display.

(clobber = no) [boolean]

Boolean flag specifying whether or not the output Table file can be overwritten, if it already exists.

EXAMPLES

1. Find the local peaks in Arlac data run with a 12" detect cell size.
