We use assumptions of point source and source-plane approximation for minimization. We find that our parametric model well reproduces the positions of multiply imaged galaxies and quasars and time delays between quasar images. We find that the best-fit centroid of the dark halo (NFW) is quite consistent with the distribution of gas from observed X-ray. Radius enclosed mass profile and mass profile from hidrostatic assumption on distribution of gas from X-ray agree quite well with each other, including the radial slopes of the profiles with average discrepancies, Mlens/MX = 1.52 on the outer radius of images. Existence of dominant galaxy associate with compactness of cluster as lens. We find increasing of fraction of galaxies morphology from distribution of cluster members increase with redshift.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]discrepancy,Galaxies cluster,gravitational lensing[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4930662[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
