Name

Usage

spec_s2n input

Parameters

input

Name(s) of multispec-format image(s) to process.

Description

If multiple images or apertures are specified, the quadrature sum of the S/N values for all spectra is printed.

Examples

1. Compute the median S/N in spectrum 24des0073cy.ms.fits:

   wm> spec_s2n 24des0073cy.ms.fits
     Image: 24des0073cy.ms.fits  S/N: 3.6 per pixel (median)

2. Compute the median S/N of all spectra in a dataset:

   wm> spec_s2n *.ms.fits
     Image: 24des0073cy.ms.fits  S/N: 3.6 per pixel (median)
     Image: 24des0074cy.ms.fits  S/N: 3.1 per pixel (median)
     Image: 24des0075cy.ms.fits  S/N: 3.6 per pixel (median)
     Image: 24des0076cy.ms.fits  S/N: 4.4 per pixel (median)
     Image: 24des0077cy.ms.fits  S/N: 7.7 per pixel (median)
     Image: 24des0078cy.ms.fits  S/N: 6.9 per pixel (median)
     Image: 24des0079cy.ms.fits  S/N: 8.0 per pixel (median)
     Image: 24des0080cy.ms.fits  S/N: 9.1 per pixel (median)
     Image: 24des0081cy.ms.fits  S/N: 9.8 per pixel (median)
     Image: 24des0082cy.ms.fits  S/N: 6.8 per pixel (median)
     Image: 24des0083cy.ms.fits  S/N: 10.0 per pixel (median)
     Image: 24des0084cy.ms.fits  S/N: 10.6 per pixel (median)
     Image: 24des0085cy.ms.fits  S/N: 10.2 per pixel (median)
     Image: 24des0086cy.ms.fits  S/N: 9.3 per pixel (median)
     Image: 24des0087cy.ms.fits  S/N: 9.3 per pixel (median)
     Image: 24des0088cy.ms.fits  S/N: 9.9 per pixel (median)
     Image: 24des0089cy.ms.fits  S/N: 7.7 per pixel (median)
     Image: 24des0090cy.ms.fits  S/N: 8.0 per pixel (median)
     Image: 24des0091cy.ms.fits  S/N: 7.7 per pixel (median)
