Use
Dynamic PSF can be called from two different ways depending on what you want:
 * You may want to fit just one star. In this case, after drawing a selection around an unsaturated star (this is important for the accuracy of the result) you can either type "PSF" in the prompt of the console or do a right click and choose the "PSF" item. In both case you will be able to copy the result and paste it where you want. In this cased a relative magnitude is computed following $$ -2.5\times \log I$$ where $$I$$ is the total intensity of the fitted star.
 * In the case you want to deal with many stars and average it, you MUST work on the dynamic PSF window by ever clicking on the "Analysis" menu and the "Dynamic PSF" item or drawing a selection around an unsaturated star, doing a right click and selecting the "Pick a star" item.
