摘要：

When a circularly symmetric function with finite support is expanded into a series oi Laguerre-Gauss functions the pertaining spot-size can be chosen at will. However, if the series is truncated the choice of the spot-size affects the truncation error. We suggest a simple rule for minimizing the error. The application to the circ function is discussed in some detail.
