# 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

#### 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

## SPIRE

### Common Pipeline

• Only minor changes in logs and documentation.

### Photometer Pipeline

• Pipeline scripts:
• Comment out optical and electrical crosstalk corrections
• Removed plotting blocks
