What class is TH1?

What class is TH1?

TH1 is the base class of all histogram classes in ROOT. Smooth bin contents of this histogram. Returns the Standard Deviation (Sigma). For axis = 1,2 or 3 returns the mean value of the histogram along X,Y or Z axis.

How many bytes does TH1 consist of?

TH0/TL0 & TH1/TL1 These two registers TH and TL are timer high byte and timer low byte, 0 and 1 are the timers numbers. They are 16-bit registers. we give our time delays in it. since 8051 is an 8-bit micro controller, we access its register in two bytes one byte for TH(timer high byte) and one for TL(timer low byte).

How do I start root CERN?

To run the program just type: root. To start ROOT you can type root at the system prompt. This starts up Cling, the ROOT command line C/C++ interpreter, and it gives you the ROOT prompt (root[0]). -b ROOT session runs in batch mode, without graphics display.

How do you clone a histogram?

For Clone/copy an existing histogram you can use the Clone() method or the copy constructor. Note that Clone() returns a pointer to a TObject and it requires the casting to TH1 , while the copy constructor can be used only with the leaf histogram classes (e.g TH1D for a double type histogram).

What triggers Th1?

Th1-cell development begins with the secretion of IL-12 and type 1 IFNs (IFN-α and IFN-β). These cytokines are released by macrophages and DCs upon activation by intracellular pathogens.

What cytokines do Th1 cells release?

Th1 cells are most often defined by their production of IL-2 and IFN-γ but have been reported to produce a number of cytokines including: TNF, lymphotoxin, and granulocyte-macrophage colony-stimulating factor (GM-CSF).

How do I run as root?

See the section called “Root And Sudo” for more details.

1. Open the Run Command dialog by typing: Alt-F2.
2. Enter the name of the program you wish to run, prefixed with kdesu and press Enter. For example, to launch the file manager Konqueror with root privileges, type kdesu konqueror.

How do I run a root file?

You need to do two things; both from a Terminal prompt:

1. Change to the directory where you have the . run file stored.
2. Type: chmod 755 filename. run.
3. Type: sudo ./filename. run.

What is a profile histogram?

Profile Histogram. Profile histograms are used to display the mean value of Y and its error for each bin in X. Profile histograms are in many cases an elegant replacement of two-dimensional histograms.

How do I read a Th1 histogram in another root session?

Because TH1 derives from TNamed , the key identifier on the file is the histogram name: To read this histogram in another ROOT session, do: One can save all histograms in memory to the file by: For a more detailed explanation, see “Input/Output”.

How to increase the number of bins in Th1?

More… Set bin content see convention for numbering bins in TH1::GetBin In case the bin number is greater than the number of bins and the timedisplay option is set or CanExtendAllAxes (), the number of bins is automatically doubled to accommodate the new bin. More…

What does the find function do in Th1?

finds new limits for the axis so that point is within the range and the limits are compatible with the previous ones (see TH1::Merge ). More… Internal function used in TH1::Fill to see which axis is full alphanumeric i.e. More…

Why does root return the binned statistics of a range?

So even though h has only one bin and it’s still included in the range, ROOT returns the binned statistics because SetRangeUser set the bit TAxis::kAxisRange to 1. This remains true even if you zoom out:
