# What's New in HIPE 5.0

## Core system

### Plotting

* Title and label can accept LaTeX commands \textrm \textit \textbf \mathrm \mathit \mathbf. for example, V$_{\textrm{LSR}}$

### Numeric routines

#### Random Numbers

• New random numbers generators from different distribution: Uniform, Gaussian, Poisson, Gamma, Cauchy (Lorentz), Exponential and Jeffreys.

#### Statistics functions

##### New functions
• GeoMean which calculates the geometric mean of a array of numeric data types with 1 to 5 dimensions.
• Mode which returns the mode(s), or the most common element(s), of an array of numeric data with 1 to 5 dimensions.
• Covariance which yields the covariance between two random variables/vectors x and y with finite second moments. If one vector is longer than the other, only the values up to the length of the shorter vector will be taken into account.
• CovarianceMatrix which returns the covariance matrix of the input M x N matrix. The result is a N x N matrix with each i, j value equal to the covariance of the ith and jth columns of the original matrix.

### Images

#### Display

• Images can be opened as RgbImage directly from the Navigator in HIPE.
• Regular image files (jpg, gif, png, ...) are shown as preview in the outline when being clicked on in the navigator view of hipe.
• 2 images can be compared by setting the opacity of the image. This can be done using the setOpacity(float) method or using a slider in the Image Display.

#### Analysis

• Added the methods containsNorthCelestialPole and containsSouthCelestialPole on the Wcs.
• Regridding an image on the grid of another image using RegridTask
• Update of URM documentation
• Cropping an image by drawing a rectangle on it
• Correction of the calculation of the dimensions of a mosaic

## PACS

### Pipeline

• PACS "New Style Sliced" pipeline implementation is now activated
• PacsSpr:2647 : phot and spec ipipe script names are changed to be more logic and intuitive
• Pipeline Script access
• HIPE -> Menu -> pipeline -> PACS
• Calibration framework Calibration products are no longer delivered with the build in a local store.
Calibration products are now delivered as a directory of FITS files.
This directory with calibration products can be found in the data/pcal sub-directory of your installation directory.
HIPE> fm = getCalTree(verbose=1)
The calibration framework is adapted and will read these FITS files by default.
The getCalTree() command and all access to calibration data has not changed, under the hood, the local store has been replaced by the directory of FITS files. Other small changes:
• getCalTree(), getCalProduct() now understand the 'verbose=True' keyword and will print information on the location of the calibration products.
• getCalProduct() the third argument, 'version', is no longer mandatory, if not given, the last version of the calibration product will be returned.
• a new Pacs Documentation page has been opened on the public wiki.

#### Photometry

• Extended Madmap (using scan and cross scan) for interactive usage
• HIPE -> Menu -> pipeline -> PACS -> L2_scanMap.py
Based on HCSS-9361, a prototype for the extended Madmap pipeline is now available in HIPE for interactive usage. The extended Madmap pipeline is designed to combine scans and cross-scans in order to produce optional map. Unlike DP pipelines (which normally starts with one ObservationContext), this pipeline takes an obsList (an ArrayList) which is a list of ObservationContext. The pipeline will run even there is only one obs in the obsList. Below is an example creating an obsList:
HIPE> obsList=ArrayList()

• New script for scan Map pipeline
• PacsSpr:2801 Proposal for a two-stage photometer pipeline with masked highpass filtering
• Now THE standard processing script for scan maps
• Photometer Mapping
• PacsSpr:2853: Photometer mapping accepts a variable input pixelsize (parameter pixfrac in the PhotProjectTask and the MapIndexTask).
• PacsSpr:2789: The MapIndexViewer has a Sigclip gui to display the effect of different Sigclip parameters on the second level deglitching. Now it is not necessary any more to guess Sigclip parameters, run the deglitching and check the quality afterwards. The new option allows to find the best parameter quickly BEFORE deglitching has been applied.
The MapIndexViewer now also displays the signal vectors in the "timeordered" mode.
• PacsSpr:2921: the MapIndexViewer shows mean/median +/- error permanently in the signal plot
• PacsSpr:2807: the Full MapIndex needs less memory than before
• PacsSpr:2859: Wcs4mapTask got a crota option to manually set the requested rotation angle of a map.
• PacsSpr:2925: CorrectRaDec4SsoTask is now also accepting the new Horizons class definition. An example how to use it can be found in the attached
• PacsSpr:2751 : photProject error map has been checked for NaN
• PacsSpr:2543 : exposure map has been removed in favour of the coverage map
• Noise treatmement
• PacsSpr:2752: A new modul herschel.pacs.spg.phot.PhotAddNoisePerPixelTask provides 4 ways to calculate the initial photometer noise. *Noise propagation is also implemented in the HighpassFilter, Mean- and MedianFilters.
• Pointing
• Others
• PacsSpr:2761 PACS EDP: phot pipeline adaptation to cope with variable scan velocity
• framesOut = photMaskFrames(framesIn [,beforeFirstScanLeg] [,noScanData] [,afterCalblock=0] )
• beforeFirstScanLeg : Mask data befor the first scan leg
• noScanData : mask data where the ScanBBID is not set (includes turn arounds)
• afterCalblock : Mask n data after calibration block
• HcssSpr:6681: Sigclip can be applied n-times in one go.

#### Spectrometry

• new AOR mode "unchopped" including improved spatial calibration:
• First draft of the unchopped mode pipeline added to the build
• PacsScr:2779: a "newstyle" unchopped mode pipeline is in place which can be run automatically or interactively
• PacsScr:1048 New task specSubtractOffPosition implemented for unchopped pipeline
• new interactive tool SpectrumExplorer:
• improved wavelength calibration:
• PacsScr:2964: new wavelength calibration applied in waveCalc task using the wavePolynomes cal file
• spectrometer trend analysis product for the calibration blocks:
• PacsScr:2777: calibration block trendAnalysis product added to the observation context

### Calibration

#### Spectrometry

• PacsSpr:2488 : New Wavelength Calibration Product
• PacsSpr:2855 v8 of the Pacs Spectrometer Array to Intrument and v4 of the Module2Array cal file is inserted in the system. This generates correct values also for center chopper positions (unchopped and waveswitch mode).
• PacsSpr:2715 : updated spectrometer spatial cal file --> PCalSpectrometer_ArrayInstrument_FM_v6.fits
• PacsSpr:2607 The RSRF calibration tables contain "NaN" which are then introduced into the signal by rsrfCal
