Detection of this redshifted 21 cm signal is one of the key science goal for Square Kilometer Array (SKA-1) low. One of the major challenges for the detection of this signal is the accuracy of the foreground source removal. The foregrounds are composed of the diffuse galactic synchrotron emission and extragalactic compact and extended sources. The flux densities of these sources are 10 4 - 10 5 times stronger that the faint resionziation signal of interest. Here, we investigate the level of accuracy for the calibration and bright source removal algorithms from the reionization data-sets that will be observed with the SKA-1 low. For this, we use the recently developed OSKAR package in order to simulated the response of the tile response from each of the SKA1-low stations. Later, we analyze the data in CASA (NRAO) package. |
