# GempakMosaicImgLinkRequest
#
# This code has been developed by the SIB for use in the AWIPS2 system.
# Performs a BaseRequest for a Mosaic image from GEMPAK, and stores
# the image data in the uEngineProducts directory for later transfer.
#
# Usage:
# import GempakSatHdrRequest
# dataRequest = GempakSatHdrRequest.GempakSatHdrRequest()
# dataRequest.setPhysicalElement("...")
# dataRequest.setSectorID("...")
# dataRequest.setTime("090519/1100")
# return dataRequest.execute()
