Abstract: The Space Telescope–European Coordinating Facility (ST-ECF) has started, together with the STScI and the CADC, a project to build a Hubble Legacy Archive that includes high level and VO-ready data products. The main focus at the ST-ECF is to provide extracted spectra from slitless spectroscopic HST data. In this contribution the Pipeline for Hubble Legacy Archive Grism data (PHLAG) is presented. PHLAG performs an unsupervised reduction of slitless data taken with the ACS or NICMOS and ingests the VO compatible spectra into a post-mission archive. The various sub-components of PHLAG— data preparation, data retrieval, image combination, object detection, spectral extraction using the aXe software, quality control—and their mutual interplay are discussed. In a pilot study PHLAG is applied to NICMOS data taken with the G141 grism.
