Settings Window


The Settings window allows certain XSNOED settings to be changed. All settings changes take effect immediately, so the effect of the OK button is simply to close the Settings window. The Cancel button closes the Settings window and restores all settings to the state they were in when the window was initially opened. Note that the default state of each setting is defined in the XSnoed resource file.

The following is a list of available settings:

GTID's: Decimal / Hexadecimal

Sets the display of event Global Trigger IDentification numbers to hexadecimal or decimal. When displayed in hex, the GTID numbers will have a leading '0x'.

Angles: Degress / Radians / None

Sets the angle display in image windows to degrees or radians. The 3-D and projection images show the detector rotation angles if moved from the Home position. The angle display can be disabled by selecting the None radio button.

Times: Sudbury / Local / UTC

Changes the event time display between Sudbury time, local time and UTC. The label in the Event Info window changes between "Time:", "Loc Time:" and "UTC Time:" depending on the time display setting. Sudbury time is Eastern Standard Time, with daylight savings time when applicable. Local time is the time local to the system where XSNOED is being run. UTC is Universal Time Coordinates.

Hit Info: Show Hit XYZ

Toggles on and off the X-Y-Z display in the Hit Info window.

Settings: Save Settings on Quit

With this option selected, all settings including menu options and window locations are automatically saved to the XSnoed resource file in the user's home directory when XSNOED is quit. The File/Save Settings menu item saves these settings immediately.

Hit Size

Sets the multiplication factor for the size of hits in all event views (except the crate image). Normally this should be set to 1.0, but sometimes it is useful to increase the hit size for very low NHIT, or decrease it for high NHIT events.

NCD Size

Sets the multiplication factor for the size of the NCD tubes in the 3-D display. If displayed at true size, the NCD's are so thin they can be difficult to see, so this setting allows the size of the NCD's to be enhanced to make them more visible.

Label

The Label checkbox turns on the image labels. The labels appear below each image in every XSNOED window. This option is designed to provide extra information in printed images, and can also be turned on via the Print dialog. After image labels are enabled in the settings, they can be hidden in individual image windows by simply clicking on the label. Another click at the bottom of the image causes the label to re-appear.

The buttons to the right of the Label checkbox provide some basic control for common label quantities. The Clear button clears the label string. The +Run, +GTID and +Time buttons add the run number, event GTID and time respectively to the label string. The label format string displayed below these buttons and can also be edited directly.

The label format string may be edited to contain any desired text. As well as the quanties added by the buttons, there are a host of quantities which may entered manually into the label string. All format specifications begin with a '%' symbol and end with a format code. Floating point formats may contain an optional precision specifier before the format code (ie. %.4dm shows the data minimum to 3 decimal places). Most format format codes are two characters long, with the exception of "%" which adds the % symbol to the label, "/" which adds a newline character, and "+" which specifies the big label font. The default label string is "Run: %rn GTID: %gt", which shows the event run number and GTID.

The table below gives a full list of available codes for label format specifications:

Code Name Format Description
rn Run Number int The run number for the displayed event.
sr Sub-Run int The sub-run number for the displayed event.
gt GTID int Event global trigger ID (GTID), expressed in decimal or hexadecimal depending on the current settings.
ti Time hh:mm:ss.ss The event time. Seconds are floating point with a default precision of 0 decimal places. Expressed in the time zone specified by the settings. If the time zone is local or UTC, "Loc" or "UTC" respectively are appended to the time string. No extra designation is appended for the Sudbury time zone.
da Date mm/dd/yyyy The event date. Expressed in the time zone specified by the settings.
nh NHIT int The event NHIT (total number of channels participating in the event). See the NHIT description in the Event Info window section for a detailed explanation.
no Normal int The number of normal PMT's in the event. See the description in the Event Info window section for details.
ow Owl int The number of OWL (outward looking) PMT's in the event. See the description in the Event Info window section for details.
lg Low Gain int The number of low gain PMT's in the event. See the description in the Event Info window section for details.
fe FECD int The number of FECD (Front End Card Digitizer) channels in the event. See the description in the Event Info window section for details.
bu BUTTS int The number of BUTTS (Berkeley Underwater Tube Testing Sled) PMT's in the event. See the description in the Event Info window section for details.
ne Neck int The number of neck PMT's in the event. See the description in the Event Info window section for details.
dt Data Type string The data type displayed in the hit color scale (see the Data menu for a list of types).
dm Data Min float The minimum value of the data color scale as set in the Event Histogram window, with a default precision of 1 decimal place.
dx Data Max float The maximum value of the data color scale as set in the Event Histogram window, with a default precision of 1 decimal place.
pk Peak int Analog trigger peak measurement (see the section on the Event Info window for details).
in Int int Analog trigger integration measurement (see the Event Info window for details).
df Diff int Analog trigger differential measurement (see the Event Info window for details).
tr Trigger string The event trigger bits set (see the Trigger bit names table for a list of trigger names).
en Event Number int The event serial number (not to be confused with the GTID).
fn File Name string The name of the currently open data file.
fp Fit Position float (x3) The XYZ coordinates of the fit vertex in centimeters, with a default precision of 1 decimal place.
fd Fit Direction float (x3) The XYZ cosines of the fitted event direction, with a default precision of 3 decimal places.
fr Fit Radius float The distance from the fit vertex to the center of the detector in centimeters, with a default precision of 1 decimal place.
ft Fit Time float The fitted event time in nanoseconds, with a default precision of 2 decimal places.
fq Fit Quality float The quality of the fit (see the section on the Fitter window for more details). The default precision is 2 decimal places.
nf Num Fit int The number of fitted PMT's in this event.
sd Sun Direction float (x3) The XYZ cosines of the direction towards the Sun at the time of the event, with a default precision of 3 decimal places.
sa Sun Angle float The angle between the fit and sun directions. Expressed in degrees or radians depending on the angle display setting, with a default precision of 1 or 3 decimal places respectively.
pt Previous Time string The relative time between this event and the previous event, with units string.
nt Next Time string The relative time between this event and the next event, with units string.
% Percent string Adds the '%' symbol to the label string.
/ Newline string Adds a newline character to the string, allowing mult-line labels.
+ Big Font - Uses the big label font for the line containing this specification. The label fonts are set in the XSnoed resource file.

Reset Event Sum

This setting causes the event sum to be reset at the specified interval, as if File/Clear Event had been selected from the menu. This option is useful when viewing live dispatched data. Note that the sum is not cleared if data stops arriving.

OK

Confirms settings changes and dismisses the Settings window.

Cancel

Cancels all settings changes and returns settings to their values at the time when the Settings window was opened.
