8 PACS CoP & PV Review 21/22 Jan 2009 PVSpecWave8 PVSpecWave: The spatial situation 43.9” Diameter of Jupiter Mid-Jun-09 as seen from L2 White crosses indicate location of all PACS spectrometer spatial pixels

9 PACS CoP & PV Review 21/22 Jan 2009 PVSpecWave9 PVSpecWave: Spatial Information about Targets Fluxes of moons and faint ring are being neglected Roll-angle will be important for assigning rotational velocity shifts separately for each spatial pixel (max. Δ λ ~11km/s) Check that no other bright targets come close to Jupiter at actual observation date/time. Require Herschel velocity towards target and doppler shifts

10 PACS CoP & PV Review 21/22 Jan 2009 PVSpecWave10 Status of Analysis and Uplink Preparation Analysis code (or CAP) is unchanged from FM ILT - Operating system: MS WinXP - Use HIPE to generate L0 products - Use IDL code to derive new calibration parameters - Output = ASCII files of polynomial coefficients for inclusion into pipeline Updated input model spectra for all giant planets are available now covering the entire PACS wavelength range and convolved to the PACS spectral resolution, inclusion of HD lines in progress For the overall calibration strategy and formalism see presentation at the Herschel Calibration Workshop#2 Uplink (1 st version) is defined in X-HSPOT proposal PVSpecWave No relevant SOVT data available for analysis Semi-Automatic calibration procedure

11 PACS CoP & PV Review 21/22 Jan 2009 PVSpecWave11 Calculated fluxes for 1 spatial pixel
