NAME

snrmap -- Generate a net counts signal-to-noise map at sub-cell resolution

USAGE

snrmap image snrimg

DESCRIPTION

SNRMAP generates an image of net counts signal-to-noise at detect sub-cell resolution from an input image of raw counts at the same resolution (the output of cellmap).

PARAMETERS

image = "" prompt = Input xray image

Required Input Image at detect subcell resolution. Output of CELLMAP.

snrimg = "" prompt = Output snrmap image [root_snr.imh]

Required Output filename. SNR image map at detect subcell resolution. Input to LPEAKS.

(clobber = no) [boolean]

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

EXAMPLES

1. Generate a signal-to-noise ratio map data at detect sub-cell resolution.


de> snrmap
Input xray image : harlac12
Output snrmap image [root_snr.imh]: .

Convolving 3x3 cells

Convolving 5x5 cells

Calculating Snrmap with equation:

snrmap=(1.7777*cell3-frame)/((1.7777**2*cell3+oframe)**0.5)

Writing Snrmap Image:
./harlac12_snr.imh
