Detection of polarised radio sources: IFCAMHW

IFCAMHW We provide IFCAMHW, a MATLAB package that implements the Mexican Hat Wavelet Family of filter [1], [2] for the detection/estimation of the total intensity emission from compact sources in microwave sky maps.


The open source code is publicly available here.

Installation and dependencies.

The codes are written in MATLAB. The code is provided as gzipped tar file containing six code files plus five example files with extension .DAT.

The .m files should be installed in a directory inside the MATLAB path. No additional installation steps are required.
