The Menu Option Switches

Selecting an option will light up (gold colored) the corresponding menu item and vice versa. Currently the only fitter results that can be examined come from the time fitter.

FILE

QUIT DISPLAY

quit display completely with SNOMAN continue to run

QUIT VIW

display goes to sleep, may be reactivated (not used)

POSTSCRIPT

creates a full color postcript file (EVENT.PS) in the local directory for the present event.

(Note : the default page for EVENT.PS is quite big. To scale it down to a 8"x11" size, edit the file and change

scale 0.25 0.25

to

scale 0.20 0.20

before printing. Only one change is needed.)

HIGZ RZ

creates an RZ picture file (snopict.higz) in the local directory which contains all known HIGZ pictures currently in memory. (See 5.9 for more information.)

EVENT

INFO

pop up window to show event information

NEXT

get next `new' event

DISP

PSUP

show PSUP (switch off for Mini-SNO!)

D2O

show acrylic vessel (switch off for Mini-SNO!)

XYZ-AXIS

show xyz coordinate. The label dims when the axis is pointing to the rear

ALL PMT

show `all' fired phototubes

NOISE PMT

show monte carlo noise tubes (Note: to display the noise tubes `only' one should leave NOISE PMT on and ALL PMT off).

VERTEX(FIT)

show fitted vertex by joining the pmts to the fitted vertex with a straight line. The portion of the line inside the D2O is accented with a bright blue color.

VERTEX(MC)

show initial monte carlo source cone (the first outgoing track).

PHTN(HIT)

show monte carlo photons that score a phototube hit.

PHTN(MIS)

show undetected monte carlo photons

USER_DEV

call the user provided routine DSP_USERITEM and draw on present screen.

HISTO

REFRESH

redraw histograms on opened histogram windows

TIME DISTRIBUTION

show time distributions

TUBE STATISTICS

show a scatter plot of time versus charge for all tubes

VIEW

VERTEX VIEW

place the fitted vertex at the origin of the display.

PROJ

$\theta$ vs. $\phi$

As the name indicates.

GALL

Gall's stereographic projection. Its main characteristic is that preserves area (an thus, density). The worst distortion is near the poles, the distortion zero at $\pm$ 45$^{\circ}$ latitude (45$^{\circ}$ and 135$^{\circ}$ polar angle). Distortion is reasonably small close to the equator.

MERCATOR

Mercator projection. Very common projection, preffered by seamen because the angles are preserved. Distortion is zero at the equator and grows with latitude.

SINUSOIDAL

Sinusoidal projection. Distortion is zero at the center of the map.

AZIMUTHAL

Azimuthal projection. Only half a sphere is mapped. The two circles on the bottom of the window are the north and south pole projections. The top circle is a projection that can be centered at any point dragging on the main sphere.

USER

Calls user defined projection.

B-W

When selected, maps are shown on black and white.

VERTEX COL

full color picture of the event as viewed from the reconstructed vertex and along the track direction. If no track is fit, or the fit vertex is far outside the detector ($r > 12$ m) the event is depicted as seen from the center of the detector, looking up.

VERTEX BW

grey scale version of above.

MMOUSE COL

full color picture including two 2D views of the event. First view has top and bottom hemispheres as seen from the vertex looking up and down respectively. Second view has full detector unfolded as a sky map. The two views combined make up a picture that looks like a silhouette of a popular Disney character.

MMOUSE BW
