This code gives an estimation of the accuracy of the magnitudes at
maximum and minimum luminosity given in fields 42 and 43. This estimate
includes the errors of individual measurements and the possible
variability of the maxima and minima. This information is given for
stars with a variability code of 3 or 4 (as specified by the first
digit of field 26), whenever the necessary information on the
luminosity curve was available. The code can take the values given in
Table V3
.
