Abstract :
We present the imaging and calibration of the Giant Metrewave Radio Telescope (GMRT) visibility data through an analysis pipeline developed in GLISH using the framework of AIPS++. Starting with initial visibility data this analysis pipeline can be run in a completely automated fashion resulting in final data products, namely image along with the source catalogue. The pipeline has been used for making close to thermal noise limited images at all bands of operation of the GMRT, producing some of the high quality. A good source model building along with other tasks of AIPS++, essentially automates the complete analysis procedure.
