USE_TAU ---------------------------------------------------------------- This is a flag to indicate whether a TAUCAL file will be used in this application. ---------------------------------------------------------------- . CALFILE ---------------------------------------------------------------- This is the name of the TAUCAL file. ---------------------------------------------------------------- . OBSRUN ---------------------------------------------------------------- This is the run number associated with the OBS cube ---------------------------------------------------------------- . WHICH_RVT ---------------------------------------------------------------- This is the number of the RVT to use this time. ---------------------------------------------------------------- . WHICH_RVF ---------------------------------------------------------------- This is the number of the RVF to use this time. ---------------------------------------------------------------- . EST ---------------------------------------------------------------- This is the method of estimation to be used. There are four possibilities (1) use the estimate from the ring just before the OBS run, (2) use the estimate from the ring just after the OBS run, (3) use an average of the above, (4) do an interpolation of the above. ---------------------------------------------------------------- . DISP ---------------------------------------------------------------- You may, if you wish, display R, Xc and Yc versus time. ---------------------------------------------------------------- . CAL_CUBE ---------------------------------------------------------------- Answer yes if this is the CAL cube which was used to define the RVT you are currently examining. ---------------------------------------------------------------- . IGNORE ---------------------------------------------------------------- If you want, you may ignore dr (and its implied value of dz) only calculate values of dx and dy. ---------------------------------------------------------------- . NAME_RVT ---------------------------------------------------------------- This is the name of the RVT file as opened in RINGS. ---------------------------------------------------------------- . XCEN ---------------------------------------------------------------- This is the X position of the optical axis. ---------------------------------------------------------------- . YCEN ---------------------------------------------------------------- This is the Y position of the optical axis. ---------------------------------------------------------------- . NSERFIT ---------------------------------------------------------------- This is the total number of series actually fit in EXAM_RVF ---------------------------------------------------------------- . FITDATA ---------------------------------------------------------------- This is the series number, slope, its error, intercept and its error from each series. Actually all that is needed is the slopes and their errors so you can get away with typing rubbish for the other four... ----------------------------------------------------------------
