Plots to make

Why do we select proton or iron as our UHECR candidates?

1. Proton and Iron are very common in our universe.
2. Iron has the highest binding energy among heavier nuclei, in other words, they are hard to break up in the GZK process.
3. There might be some other elements blow GZK threshold, but these two are kind of the limit.

Root set thstack axis title

First, do this
stack->Draw("nostack");
Then this
    stack->GetXaxis()->SetTitle("Timebins");
    stack->GetYaxis()->SetTitle("Signal(VEM)");
If you do not follow this order, you get error, stupid root!

None of these five methods works well with 45 degrees, should try smaller zenith angle to check.

Find out it is not the zenith angle problem, the distance problem. My methods works better for the the muon number further away from the core(1.2km-1.6km) than 0.6-0.8km.

It also only happens for the new data. Epos2

2. add weight to peaks with the size of the peaks
3. find out Num muon true meaning in Garrido's GAP Notes

The way to ignore the biggest peak in fitting is set it to average of the previous and following bins

How exactly was muon jump drop and peaks defined?

ubuntu touch pad not working after login

Try this
$gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
Worked for me

ppt里的是用的jump fit plot

Risetime

Which risetime was used in the data?
10->50
or
10->90


知道了
是
for each triggered tank, we define rise time as the time for the signal to go from 10% to 50% of its total value.

g++生成a.out以外的执行文件

To compile a C or C++ program:

% gcc file.c

or

% g++ file.c

This compiles file.c into an executable binary named a.out.

Here are a few options to gcc and g++:

-o outputfile

To specify the name of the output file. The executable will be named a.out unless you use this option.

% g++ file.c -o test

-g

To compile with debugging flags, for use with gdb.

-L dir

To specify directories for the linker to search for the library files.

-l library

This specifies a library to link with.

-I dir

This specifies a directories for the compile to search for when looking for include files.
