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