SNRCalc

Signal-to-Noise Ratio (SNR) and Surface Background Ratio (SBR) calculation on an image.

Plugin Type: Local

SNRCalc is a local plugin, which means it is associated with a channel. An instance can be opened for each channel.

Usage

This plugin is only used in ANALYSIS mode, as defined in Ginga Configuration Files.

It is very much like SNRCalc in stginga except that SBR lower limits are customized based on QUIP operation type (“Stage Name”) in use, as tabulated below. The limits are used to determine whether the image being analyzed is acceptable. These numbers are subject to change:
