At this point, I don't know how to extract specific data of the time resolution of crystals. Would you please help me how I could calculate time resolution? I send mac files as attachments.</span><br style="color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small;">My simulation includes two <span><span style="color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small;">LYSO</span></span> crystals and a point source of 511 kev at the center between them.</span></div><br></div><div dir="ltr" data-setdir="false">Thanks a lot</div></div></body></html>
