use_rate

Set this flag to turn on rate-enabled back projection. This is particularly critical to set when the deadtimes become greater than 1/2. For dirty maps made with USE_RATE set to 0 the true source positions may have the lowest value in the field. Setting USE_RATE to 1 corrects that and the source positions will again have the highest values and appear brightest in the dirty map images. For the CLEAN algorithm to work the source positions must have the highest values.
