Interactive display and despiking
Mode = ‘p’ or pltbol (or any p∗ link to scuplot) is a wrapper around the Kappa utility linplot. It allows plots of a whole series of bolometers one by one, optionally overlaying them with the same bolometer from a second file. Obvious overlays are despiked on non-despiked data or data from different exposures to check the noise.
Mode = ‘r’ or rlinplot (or any r∗ link to scuplot) is a wrapper around the Kappa utility mlinplot. It provides plots of sets of bolometers in a single window with optionally data from a second file in a second window. Obvious files are despiked and non-despiked data or data from different exposures to check the noise.
Mode = ‘d’ or dspbol (or any d∗ link to scuplot) can be used to interactively despike bolometers. While it is not as fast as a completely integrated routine would be, it makes interactive despiking much easier by hiding the cycle between linplot and change_quality for the user. The most common use is to zoom in on the region with the spike via the ‘X’ menu option (either typing the input or using the cursor) and subsequently to flag the offending point (just type the coordinate of the point, a range, or use the cursor; in general the coordinate is to the right of the plotted point). The routine will overlay the despiked data, prompt the user to accept the new set and de-zoom to the original scale. To reset a previously flagged point, flag the point again but do not accept it: the point will be set to GOOD again. Please read the note below the description of the menu on the use of the mouse.
For each mode the menu items are a subset of:
[M. H] | Redisplay menu |
[Q] | Quit |
[N] | Next bolometer |
[B#] | Switch to bol # |
[X min max], [X cen] | X-axis from min:max or cen+/-10 |
Just ‘x’ activates the cursor. | |
[R] | Reset X-axis |
[Y min max], [Y lim] | Y-axis from min:max or -lim:+lim |
[U] | Reset Y-axis |
[#], [#:#], [#-#] | Despike point or range of points; |
Just ‘p’ activates the cursor. | |
Option > | |
Note that a X center defined with the cursor or [X cen] defaults to a 20 points window around cen, the position of the spike. Using the CURSOR, the Left Mouse button always defines the point, the Right Mouse button exits the cursor task while accepting the last point clicked.

except that a whole set of bolometers is plotted in a
window (equivalent to rlinplot). If the overlay comes up scrambled, delete the agi_xxx files in your home directory and if that does not work also files like linplot.sdf in the /home/you/adam subdirectory.
