Transitioning the Hubble Legacy Archive (HLA) to Normal Pipeline Operations

The Hubble Legacy Archive (HLA) has been producing high-level drizzled science products with data
obtained by several Hubble Space Telescope (HST) instruments . These include coadded,
mosaiced images and source catalogs from single-visit and cross-proposal exposures. The
generation of these products, however, often requires highly interactive and intensive manual
intervention, especially in the construction of the Hubble Source Catalog (HSC), that makes it difficult
for routine generation of these products in an automatic pipeline.
We report here recent advances, notably improvements in astrometric corrections achieved by matching to the Gaia catalog, that remove the dependency on the HSC and allow us to transition the HLA from campaign-style data releases into part of the standard HST data processing
pipelines for two of the main imaging instruments, the Advanced Camera for Surveys (ACS) and the Wide Field Camera 3 (WFC3). We discuss the design and development required and status update for these high-level fully automated pipelined Hubble Advanced Products (HAP), which will replace the HLA for these two instruments.
