REMARKS.
 INDICES V-B,B-U,U-W,B-L ARE EXPRESSED IN DECIMAL LOGARITHMES OF THE INTENSITY
 V OF JOHNSON IN MAGNITUDES.
 SOME PUBLICATION ONLY GIVE WALRAVEN'S V INDICE.
 THEN WE HAVE USED THE FOLLOWING TRANSFORMATIONS
 V OF JOHNSON =6.88-2.5(V-0.08(V-B)) FOR PUBLICATIONS EDITED BEFORE 1971 AND
 V OF JOHNSON=6.874-2.5(V+0.065(V-B)) FOR THE OTHERS.
 IN THE FILE CONTAINING THE HOMOGENOUS VALUES(3), WE HAVE TRANSFORMED ALL THE
 DATA EDITED BEFORE 1971,THE RESPONSE CURVES OF THE PASSBANDS HAVING CHANGED
 BETWEEN THE FIRST AND THE LAST MEASUREMENTS.
 - THE TRANSFORMATIONS -
 V*=V-0.026(V-B)-0.002
 (V-B)*=(V-B)-0.026(V-B)-0.002
 (B-L)*=(B-L)
 (B-U)*=(B-U)
 (U-W)*=0.93(U-W)  IF(U-W) L. T. 0.25
 (U-W)*=(U-W)-0.018  IF (U-W) G. T. 0.25
 * INDICATES THE NEW ADAPTED VALUES.
 FILE 3 DOES NOT CONTAIN COLOURS PUBLISHED IN THE 11001 PUBLICATION
 THE TRANSFORMATION FROM (V-B) TO THE B-V OF JOHNSON IS NOT UNIQUE,AND IT IS
 NOT POSSIBLE TO CALCULATE THE B-U,U-W AND B-L INDICES IF WE ONLY HAVE THE
 PUBLISHED UNREDDENED ((B-U)),((U-W)) AND ((B-L)) COLOURS OF THIS PUBLICATION
 WITHOUT THE ((V-B)) INDICES.
 BUT FILE 2 CONTAINS THESE UNREDDENED VALUES.
 WE HAVE DISTINGUISHED BETWEEN MICROVARIABLES -V- AND VARIABLES -V*-
 THE VALUES OF THE VARIABLES STARS HAVE BEEN OMITTED IN THE HOMOGENOUS CATALOGUE
 BUT A COMPLETE INFORMATION ABOUT THE COLOURS OF THESE STARS CAN BE FOUND IN
 THE CATALOGUE OF THE PUBLICATIONS (FILE 2)
