Some useful equations

This appendix contains some intermediate results in the calculation of the error on the slope in the case of equally spaced measurements.

The well-known expressions

#math67#
#displaymath343# (25)

and
#math68#
#displaymath347# (26)

allow us to obtain the following results for equally space measurements:
#math69#
#displaymath351# (27)


#math70#
#displaymath354# (28)

and for the parameter in the straight-line-fit error expressions we get
#math71#
#displaymath357# (29)
