calibration improvements in hipe 10 0
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).

  • 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
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.

  • 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).
