What's coming up in HIPE 8

Line: 58 to 58
 

Astronomical utilities

  • Planck class moved from spire_ia_pipeline_spec_util to ia_toolbox_astro. If you are doing an explicit import (it is not needed) you have to change it to (preferred) import herschel.ia.toolbox.astro.Planck or from herschel.ia.toolbox.astro import Planck
Changed:

  • New task astrometryFix : takes a list of known source positions (e.g., from radio observations) and will adjust the absolute pointing of map data to give the best possible agreement in overall astrometry with the ancillary data (e.g., by stacking the map at the source positions).

  • New task astrometryFix: adjusts the absolute pointing of map data to give the best possible agreement in overall astrometry with some ancillary data. This is done either by cross correlation of the map(s) with ancillary map data, or by stacking the map(s) at a list of known source positions (e.g., from radio observations).
 

Numeric routines

Data fitting

Source extraction

Added:
>
>
  • Improvements to handling of pixel coordinates and region of interest in sourceExtractor* tasks:
    • Output source list now contains pixel coordinates of source (x, y) = (column, row)
    • Added "getWcs" and "setWcs" methods to the SourceListProduct/Dataset
    • Added "roi" parameter (region of interest) to tasks
    • Removed "corner*" and "returnPixelCoordinates" parameters from tasks
  • Non-standard columns are now accepted in a SourceListDataset, e.g., when converting from a TableDataset (an exception will be thrown if there are no standard columns at all)
  • Removed "subtractMedianBackground" parameter from sourceExtractorSussextractor (it didn't do anything)
  • Minor bug fixes, performance improvements and various internal changes
 

Images

Display

  • The methods addCircle, addEllipse and addRectangle is not longer dependent on the zoomfactor of the image.
Line: 219 to 228
 The Average Spectra module no longer supports the bandEdge parameter. This parameter was used only for the module's defunct outlier rejection functionality, and so it is no longer needed. Please ensure that your scripts do not use this parameter.

Interactive Analysis and Tools

Added:

Destriper

 The following new features are introduced in Hipe 8:
  • Level 2 deglitching is available through setting l2DeglitchRepeat parameter.
  • The 5 individual output parameters are combined to one ArrayList parameter where each of 5 parameter can be retrieved base on its position.
Line: 235 to 246
 
  • The input parameter name "Tod" changed to "tod".
  • The input parameter name "L2DeglitchRepeat" changed to "l2DeglitchRepeat".

Baseline Removal

 
Changed:
<
<
>
>
  • New "roi" (region of interest) parameter for baselineRemoval* tasks, specifying the region of the sky to be used in estimating the baseline
  • Removed "doInterpolation" task parameter
  • Minor changes and bug fixes (for example, the tasks now do ignore masked data samples when a TodBuffer is used internally)
