Files in this folder are related to the strong lensing model for the galaxy cluster MACS J1149.5+2223 (z=0.542), described in Grillo et al. 2016, ApJ, 822, 78, which was developed using the software GLEE (Suyu, S. H., & Halkola, A. 2010, A&A, 524, A94, Suyu et al. 2012, ApJ, 750, 10). This model was also used for the analysis of the Hubble constant with SN Refsdal time delays and multiple images in the field (Grillo et al. 2018, ApJ 860, 94).

Maps are provided for the values of convergence (k), deflection angle (ax and ay), shear (g1 and g2) and magnification (m).
 Note that the values of convergence, deflection angle and shear are given for a D_ds/D_s = 1.
 Before using them, they have to be properly rescaled according to the redshift of a source.
 Note that the values of magnification are given for a D_ds/D_s = 0.533729, corresponding to z_l = 0.542 and z_s = 1.488 (MUSE redshift of Refsdal).
 
 For each quantity, there are two maps: *_c (core) and *_l (large). 
 The first ones (*_c) cover a square region, 60" across, centered on the BCG and with a pixel scale of 0.03".
 The second ones (*_l) cover a square region, 180" across, centered on the BCG and with a pixel scale of 0.09". 

 For each quantity and region, three maps are provided: *.fits, *_l.fits (lower), and *_u.fits (upper).
 The first one shows the median values, the second and third ones, respectively, the lower and upper limits at the 68% CL.
 Values are estimated from 100 models from a MCMC chain with 1000000 points (acceptance:0.13). 

 Examples:
 ax_l.fits  : median values of the x-axis deflection angle over a square region, 180" across, centered on the BCG and with a pixel scale of 0.09".
 m_l_u.fits : upper limit values (68% CL) of the magnification over a square region, 180" across, centered on the BCG and with a pixel scale of 0.09".
 k_c_l.fits : lower limit values (68% CL) of the convergence over a square region, 60" across, centered on the BCG and with a pixel scale of 0.03".
