#   This file contains density values (2) against temperature (1) of a
#   common liquid crytsal (MBBA). At about 45.6 degr. there occurs a
#   phase transition indicated by the anomaly.
#
#   Columns (3) and (4) contain weights for a straight line fit
#   preferredly in the low temperature range and in the high temperature
#   range, respectively. Of course not a very senseful approach but
#   a good demo to see the effect of weights in a fit.
