1. Round Table Discussion Of Spectroscopic Processing & Products for the Scientific Legacy Nov 16, 2012HST Spec Pipeline & Legacy Products Round Table Kaiser, Bowen, Charlton, Lehner, Stanghellini1

2. Pipeline Processing & Products Round Table Goals -- Identify & Prioritize: When is the best legacy is ADDITIONAL DATA OBSERVATIONS Calibration data should be obtained to increase the fidelity of the data products - wavelength calibrations - flat field related observations Data products & supporting algorithms that will enable and extend the scientific utility of HST spectroscopy - optimal extraction (faint targets) - LSF availability (library) - wave cal (COS: global solution across modes) - flat field (L flat, P flat, FP-pos, fourier transform, D 2 lamp obs) - time preview capability – extract temporal slices, as fn of bandpass - High Res ( 2048x2048, R~200,000 ) STIS UV – up-down 1/2 pixel correction Nov 16, 2012HST Spec Pipeline & Legacy Products Round Table Kaiser, Bowen, Charlton, Lehner, Stanghellini2

3. Pipeline Processing & Products Round Table Goals – Identify & Prioritize: Pipeline processing additions Night only data extraction, NUV G230LB stis red light leak – implementation of Lindler correction G750L scatt light & fringing correction, Long slit package improvements new FUV Cos positions, others, …. Data acquisition/ observation parameter images/thumbnails for easing interpretation and utility of the data set (eg slit overlay on image) Error flagging: reference data quality, PHD thumbnails, gain sag map, anomalous data thumbnail, bad pixel map Cross-referencing spectra within an instrument, within HST, & to other band passes/ missions Plot time sequence of observations on a target include range of instruments, click on point to preview spectrum: Merge spectra: by config, by instrument, COS + STIS, add other band passes weights, resolution, optimum filters Nov 16, 2012HST Spec Pipeline & Legacy Products Round Table Kaiser, Bowen, Charlton, Lehner, Stanghellini3

4. Database Selection Criteria Target category (cf IUE) Wavelength bandpass Resolution Signal-to-Noise Redshift Velocity Metallicity Fuzzy keywords Position angle Night-only data (airglow lines) Nov 16, 2012HST Spec Pipeline & Legacy Products Round Table Kaiser, Bowen, Charlton, Lehner, Stanghellini4

5. Database Spectral Products Galactic maps O VI High velocity clouds 21 cm emission SMC, R136, etc., with overlay of massive star observations Sophisticated co-adds: “drizzle” for spectroscopy Source or feature catalogs: lines (emission or absorption) H2 spectrum HI spectrum Fe spectrum Line identification overplots Time sequence of observations - legend keyed to instrument/ bandpass expand beyond HST observations (Fermi, Chandra, XMM, FUSE, Spitzer, …) make data points interactively linked to spectral plots Spectral plots capable of measuring equivalent widths, velocity shifts, etc., (cf VAO) CTE mitigation for STIS Nov 16, 2012HST Spec Pipeline & Legacy Products Round Table Kaiser, Bowen, Charlton, Lehner, Stanghellini5
