  6. 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.

+ 7. Find Star: This helps to find stars and point sources by defining the proper PSF and limiting magnitude. the inputs must be entered in the terminal.

+ 8. Delete Centeroid: Removing all the previously masked point sources inside a specified region.

+ 9: Edit/Add Centeroid: Changing the size of the centeroids, turning them off or adding new ones. All inputs are taken from the terminal

+ 10: ds9: Opens the fits file of the displayed image in the TV. If not band has been specified (in case of using the composite image), the use-file ('r' band for /sdss and /panstarrs) would be opened. In ds9, one can play around with the 'red' elliptical aperture, (e.g. re-center it, or resize it). The parameter of this 'red' aperture can be later on captured by GLGA TV and update the ellipse

+ 11: Contours On/Off: If ds9 is open, then isophots can be displayed. This helps to locate a proper border around the galaxy. To rotate the 'red' aperture, first select it by clicking inside it on ds9. You see four selection points around it. Press Shift-key on keyboard and choose one of the four point to rotate the ellipse by dragging the mouse. To move the ellipse, click and drag ...
