16-jun-13ffwalign_row_r600102_t4.png align_col_r600102_t4.pngFirst attempt to produce correlation plots between sensors for run 600102 similar to those produced by Tamsin.
13-jul-13ffwplots_13July13_ffw.gtarCollection of noise, pedestals, cluster plots, correlation, chareg sharing  for 6 sensors and  3 types of sensor used in run 600102
15-July-2013ABnoise_e.pngNoise obtained from PTC scans for the three types of sensors. Sensors 8 (Hi Res, Low Vt), 9 (Std Res, Low Vt) and 17 (Std Res, Std Vt) were used for this plot.

Various plots for reference and strixels for the 3 flavours of StdVt, StdLowVt and HiResLowVt

Std/HighRes etc.. is just a  guess based on the sensor response. Also first attempt at resolutions (pixels_ref_all.pdf).
    

 

Consistent Plots

To achieve consistent plot styles for the papers and presentations:

  1. Copy RooCherwellLogon.C and RooCherwellAlias.C
  2. Create or edit .rootrc so it contains the lines:
Rint.Load:  RooCherwellAlias.C
Rint.Logon: RooCherwellLogon.C

When you load ROOT, these files will define a "Cherwell" style e.g. the following code shows how to use it

void test_style() {

  gROOT->SetStyle("Cherwell"); // use cherwell style

  // create a histogram
  TH1F *h1 = new TH1F("h1", "title", 100, -3, 3);

  h1->FillRandom("gaus"); // fill with gaussian

  h1->GetXaxis()->SetTitle("This is the X axis label");
  h1->GetYaxis()->SetTitle("This is the Y axis label");

  h1->Draw();

  // put "Cherwell 1 Preliminary" on the plot in default place
  CherwellSmartLabel(-1,-1,-1,"Preliminary"); // after ->Draw();

  // create some output plots
  c1->Print("example.jpg");  
  c1->Print("example.png");
 }

Plots and results

Here is a list of plots and results we need to produce.

We should also aim to produce the numbers and plots with a consistent unit e.g. uV, pA, 12-bit ADC, or electrons. If not we should have the conversion factors defined.

We need to produce some of these plots for multiple wafer types. We should agree on a standard colour scheme for the 3 types of wafer when comparing them on the same plot.

  1. Standard resistivity ("Std")                     (Black/sold line).
  2. Standard resistivity, low Vt ("StdLowVt") (Blue/dashed line).
  3. High resistivity, low Vt ("HiResLowVt")    (Red/ dotted line).

We will need to produce them for Reference, strixel, decal25 and decal50.

Each cell in the following tables should eventually have at least 3 numbers or 3 plots representing the 3 wafers

Please use a consistent naming convention: e.g.

Cherwell1_<type>_<wafer>_<description>.jpg where:

  • <type> = "Ref" or "Strixel" or "Decal25" or "Decal50"
  • <wafer> = "Std" or "StdLowVt" or "HiResLowVt".
  • <description> = short description or observable e.g. noise_v_pixel
