When they are defined, the elliptical annulus turns into yellow.97 * dash-dotted peach-color open region: If defined '(menu > SExtractor > Use-Mask)', SExtractor only uses this area for measurements. It is useful when half of the image is missing and only the area around the galaxy is useful.98 * dash-dotted green open region: If defined '(menu > SExtractor > Force-Mask)', SExtractor does not filter this area for measurements. It is useful for instance when a masked spike divides a galaxy into two halves. We do not want SExtractor fits a separate ellipse for each half.96 * [[span(style=color: #E2A76F , '''Thick dashed sky blue open regions''' )]]: These are the optional regions to measure the background value.

Save region: Normally all common-regions (Green reg.) would be saved after doing the measurement. However, once can save any change before doing the measurement. This is helpful when working with big galaxies. One should note that all band-masks are stored instantly and users should not be worried about saving their pink masks. This is because, we don not expect to have a lot of masking for each individual mask. … … 160 160 16: Original Ellipse: Use the original ellipse paramter and update the TV 161 161 162 17: Refresh TV: To reload the image and all masks.
