$ RUN COBRAG NBS*QUANT84-COBRAG Revision Date: 29 FEB 1984 Copland-Bragg internal standard analysis allowing for overlapped lines Written BY R.L. Snyder and C.R. Hubbard Run on 5-AUG-8 AT 01:05:55 Select Output Mode Desired: (Output is 132 characters wide) 1 - causes output to be put on the interactive terminal. newname - causes output to go to the named file. - causes output to go to a file named COBRA.LIS. Enter the output destination: 1 Select a print control option (I1): 0 = Full listing (input matrix, solution and final comparison 1 = Normal listing (solution and final comparison 2 = Brief listing (solution only) 2 Input the name of the Copland Bragg file output by QUANT. (default extension = .COP): CR070D Analysis of file: CR070D.COP SYNTHETIC FLY ASH MIXTURE WITH SILICON INTERNAL STANDARD. SPRAY DRIED CAMDEN HUBBARD The number of unknown phases = 3 Phase Names: MULITE QUARTZ HEMATI Enter the following number: 0.0 - Do not apply constraints to the sum of the wt. fractions #.# - Constrain solution so that the sum of the wt. fractions equal the input number (usually 1.0) 0.0 Do you wish to apply the following constraints? Each X(I) .GE. 0.0 and Each X(I) .LE. 1.0 (answer yes or no) Y Solution to be constrained such that each wt fraction .GE.0.0 AND .LE.1.0 Successful regression - all constraints both equalities and inequalities were satisfied The residual error from least squares equations= 0.764003 The residual error from equality constraints = 0.000000 ************************************ Phase Original Sample Least Sqs Name Weight Fraction e.s.d. ************************************ MULITE 0.506 0.022 QUARTZ 0.166 0.007 HEMATI 0.104 0.005 The full varience covarience matrix: MULITE QUARTZ HEMATI MULITE 1.0000 -0.8575 -0.6220 QUARTZ -0.8575 1.0000 0.5313 HEMATI -0.6220 0.5313 1.0000 $
