Input File
Overview
An example input file for HostSub_GP is provided below. This file specifies the necessary parameters in the pipeline, including regions on the 2D spectrum to be used for modeling, properties of spectrographs, as well as details in building the host galaxy prior, adaptive batching for host emission lines, and seeing matching between imaging priors and spectra. The file also includes a data block that lists the input spectra to be processed, along with their associated metadata (e.g., frametype and objid).
