Plotting data for yourself
 
Plotting data for yourself
These instructions are designed for use by JCMT staff with access to
the relevant data and programs.
TPOINT
is a powerful plotting and analysis package which is used at JCMT to
generate and update the pointing model.
Pointing data files are held at the summit in directories/filenames like
/jac_logs/20050106/20050105-173329.pnt
Copy the relevant file into your working space. The command
sequence below will provide collimations (IE & CA) and a plot of the residuals:
- tpoint
- indat yyyymmdd-hhmmss.pnt
- inmod /home/imc/pointing/models/jcmt.mod_070412
- plton xw
- fix
- use ie ca
- fit
- call a9 - - or 'g s a' or 'g a a' or 'g z z' or gdist, gscat, ghyst,
gsmap, gdist, gam etc
- gc P to produce tpoint.ps of last plot
- slist - to tabulate results/residuals
- mask n - to remove the nth datum, after which you could repeat the fitting . . .
- end
