What’s New in HIPE 10.0(SPIRE FTS)

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).

  • Updates in Spire_cal_10_1(w.r.t. Spire_cal_9_1)

    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 function

    of observational days (OD) per detector, and incorporate the result into

    The telescope model as an additional multiplicative factor.

    Improved Map Continuum and Noise (continued)

    More consistent per-detector

    results from dark observations

    (of the telescope)

    Overall standard dev. (in units of Jy) reduced

    for the dark observations for most detectors.

    New Script: Line Fitting to Spectral Cube

    Residual for all spaxels

    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).
