The current process of merging the high-resolution Dopplergrams from all six sites takes few months before these are available for analysis. This time delay is primarily caused by the arrival of data tapes at the Data Management and Analysis Center (DMAC) in Tucson, and various calibration procedures applied to the site images. Recently, DMAC has started receiving high-resolution Dopplergrams via internet on a daily basis from five of its sites (with the exception of Learmonth). In this paper, we present our recent attempts to reduce the delay between observations and the availability of merged Dopplergrams. We will also discuss how the quality of this "quick reduce" data affects the local helioseismology products.
