+The directory contains input data for computing two opacity tables:
+
+1) optab11_7f   - full table with opacities of all species;
+2) optab11_7hmc - a partial opacity table where the opacity of H, Mg, and Ca
+                  is removed.
+
+In both cases, the table has 100,000 wavelength points between 900 and 110,000 A,
+for 11 temperatures between 3 and 15 kK (spaced logarithmicall),
+and 7 densities, between 1.e-12 and 1.e-6 g cm^-3 (again spaced logarithmically).
+
+In this particular case, the resulting opacity tables optab11_7f.dat and
+optab11_7hmc.dat were not copied to the subderectory results because they
+can be downloaded separately, as explained in Paper IV
+
+The script R1 runs both test cases, however it is time-consuming, taking 
+about 26 and 45 minutes on iMac 3.4GHz for the two respective tables.
+The input data assume that the binary line lists are being used, so that
+they must exist. In the case the binary lists are not used, the user
+should make links to the ASCII files, and to make corresponding changes in
+the files *.3, e.g.
+
+'gfATO.dat'          0
+'gfMOL.dat'          0    8000.
+'gfTiO.dat'          0    5000.
+
+In this case, another possibility would be to link the three line lists
+to fort.19 (atomic list), fort.20, and fort.21, delete the fort.3 file,
+and to modify the file fort.55 by adding the last line that sets the
+number of molercular line lists to 2, having unit numbers 20 and 21.

+If one intends to compute an opacity tables to be used for cool
+(K and M) stars, one should modify the fort.3 file as,
+assuming that one has the binary lists

+'gfATO.bin'          1
+'gfMOL.bin'          1    8000.
+'gfTiO.bin'          1    5000.
+'gfH2O.bin'          1    4000.
+
+The file gfH2O.dat is available upon request, and the user may
+easily create a binary file using program LIST2BIN.
