WebDownload scientific diagram Contour plot of an electron density projection map of a p1 (acetate) crystal (unit cell parameters a 133.2 A Ê , b 269.9 A Ê , b 111.1 ) preserved in negative stain. In X-ray crystallography, a difference density map shows the spatial distribution of the difference between the measured electron density of the crystal and the electron density explained by the current model. These coefficients are derived from the gradient of the likelihood function of the observed structure factors on the basis of the current model. morris ac ms hillary fl - 34997
