Module Description
The AstroVolume can read/write FITS file (astronomical data format) and handle the color function and display of Astro Volumes.
Panels and their use
Handling the loading and writing of FITS files
The display of the Astronomical World Coordinate (WCS) and Data Probing for 2D views
The control of the display coordinates
The control of the 2D color transfer function
The control of the 3D color transfer function
Tools to convert mask from FITS files (e.g., generated by SoFiA) into segmentations objects and viceversa
Astro segmentation editor effect
This editor effect can create multiple segmentation (3D contours) of the input volume.
Contour Levels info:
The Levels can be specified as a list (e.g., 'VALUE1;VALUE2;VALUE3') or in the following format 'FISRT:LAST:SPACING'. In the case of a list, it is possible also to specify for each Contour both the MIN and MAX intensity values of the level (e.g., 'CONTOUR1MIN,CONTOUR1MAX;CONTOUR2MIN,CONTOUR2MAX'). If the string is preceded by 'RMS', the levels are evaluated in units of RMS of the datacube.
The contours in SlicerAstro are a full 3D segmentation. Therefore it can be computationally heavy to segment (marching cubes algorithm) and visualize around the noise range [-2, 2] RMS for large datacubes.
