Calibration Improvements in HIPE 10.0• The beamParam, teleRsrf and instRsrf products have been updated
to provide a separate calibration for ODs after 1011, when the BSM position was corrected to have a 0” offset.
• Telescope model coefficients updated, and separate coefficients added for off-axis detectors.
– Better map continuum and noises.
• Better calibration products for the low-resolution (LR) mode.– Better continuum flux accuracy.
• The beam profile product has been updated with the fitted 2D frequency-dependent beam shape, plus a new spatial correction coefficient calibration product.
– To be used with a new user tool to do flux correction for semi-extended sources (in HIPE 11).

Software Improvements in HIPE 10.0
• Apodization is now carried out at the end of the pipeline after calibration of the final spectra.
– Making it eventually possible to use any apodization function.
• SPIRE SpectrometerDetectorSpectrum (SDS) explorer now marks N-E orientation on a display detector foot print.
• SDS product can now be read directly into Herschel Spectrum Explorer.
• Some new user scripts for data processing/analysis:– Spectral line fitting for spectral cubes.

Improved Map Continuum and Noise
Fit a polynomial to the “drift” of normalized dark observations as a functionof observational days (OD) per detector, and incorporate the result intoThe telescope model as an additional multiplicative factor.

What’s New to Come in HIPE 11?(Scheduled for release in May of 2013?)
– Further improved flux calibration with improved telescope and instrument RSRF functions.
– Further improved low-resolution calibration products.
– Formal release of a user tool for semi-extended source flux improvement.
– Much improved calibration for observations taken with the bright-source detector setting (used for targets brighter than 500 Jy).
– …
