Receipt: # 4893-1 Partial re-do of visit 04 approved (HOPR 93053) due to mistaken filter choice. Visit 6 only includes the narrow filter, not the continuum bands, and is hence only a partial orbit.

We propose a deep probe into the AGN-host relationship in NGC 4102, a luminous LINER and a Compton-Thick (CT) AGN in the near universe (D~17 Mpc, 1''~100pc). With joint Chandra and HST observations, we propose to investigate the properties of the soft extended X-ray emission spatially and spectrally and distinguish between Seyfert, LINER, and star formation powered X-ray emission on scales from ~30pc to 5kpc. The spatial study of the hard X-ray emission (>2.5 keV), may provide key evidence of the interaction of the AGN with thick molecular clouds. We aim to measure [O III], H-alpha, H-beta, the [S II] 6717,6731 and red & blue continua of NGC 4102. Ratios between continuum-subtracted line maps will be used to make "BPT maps" to diagnose the local ionization state. The overall goals are similar to Programs #15350 (PI: Maksym), #15609 (PI: Fabbiano) and #16837 (PI: Fabbiano), as are the basic strategies. Filters and instruments are comparable to #16837, and it is a WFC3-only program. Our goal is to reach >3-sigma detection for all lines within <1 arcsec of the nucleus. This will require 4 orbits of [O III] (F502N), 4 orbits of H-beta (F487N), 1 orbit of [S II] (F673N) and <1 orbit of H-alpha (F658N). Even the faintest H-alpha regions will be detected at ~23-sigma in one orbit, so we pack the continuua into the H-alpha orbit. Given the number of exposures, it is possible to use a box dither to improve PSF sampling for [O III], H-beta and [S II]. H-alpha and continuum observations are short and use a CR-split. Pre-flash amounts are typically 17, except for F814W (12). [O III] has been re-observed due to a failed observation. H-alpha must also be re-observed, due to a failed observation. Continuum bands from the original visit are fine, only H-alpha is needed. na Supermassive Black Holes and Active Galaxies 6 false false false false false false false SUPPORTED ISM EMISSION LINE NEBULA NLR NUCLEUS This object was generated by the targetselector and retrieved from the SIMBAD database.
