Plotting the data

There are some self explanatory plotting programmes available:

• plota4l plotting normal points of the degree polarisation as a function of phase, with a file produced by kokpol as input.

• plota4c same for circular polarisation.

• plotpa4 same for position angle of linear polarisation.

• plotal plots nightly means or normal points of degree of polarisation as function of phase. The range is given for each of UBVRI.

• plotpa same for position angle.

• plotaxy plots nightly means or normal points of Stokes parameters as a function of phase. Scaled automatically, either for each of UBVRI, or from the keyboard.

• jdplotp plots polarisation as a function of Julian date.

• jdplotxy the same for p and p.

• jdplota the same for position angle.

• jdplot plots both p and its angle as a function of JD.

• hsplot3 plots UBVRI magnitudes as a function of phase from a file made by ``fotlim''.

• plota4m plots normal points of UBVRI magnitudes with error bars, made by ``fotnorm''.

• plota4mb the same but plotted over two phases.
