+      SUBROUTINE RDLIGHT
+!
+!******************************************************************************
+!  Subroutine RDLIGHT reads the polynomial coefficients for isoprene
+!  emissions from disk. (yhw, bmy, 7/6/01, 7/20/04)
+!
+!  NOTES:
+!  (1 ) Now use F90 syntax.  Now reads the file "light.table" directly
+!        from DATA_DIR so that symbolic links are unnecessary.  Also use
+!        IOERROR to trap I/O errors.  Updated comments and made cosmetic
+!        changes (bmy, 7/6/01)
+!  (2 ) Deleted obsolete code from ages ago.  Also print full pathname
+!        of the "light.table" file. (bmy, 9/4/01)
+!  (3 ) Now read file "light.table" from the DATA_DIR/biogenic_200203/
+!        directory.  Added FILENAME variable. (bmy, 3/29/02)
+!  (4 ) Deleted obsolete code from March 2002.  Now reference IU_FILE and
+!        IOERROR from "file_mod.f".  Now use IU_FILE instead of IUNIT as
+!        the file unit number. (bmy, 6/27/02)
+!  (5 ) Now references DATA_DIR from "directory_mod.f" (bmy, 7/20/04)
