16-jun-13 | ffw | align_row_r600102_t4.png align_col_r600102_t4.png | First attempt to produce correlation plots between sensors for run 600102 similar to those produced by Tamsin. |

13-jul-13 | ffw | plots_13July13_ffw.gtar | Collection of noise, pedestals, cluster plots, correlation, chareg sharing for 6 sensors and 3 types of sensor used in run 600102 |

15-July-2013 | AB | noise_e.png | Noise 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. |

25-jul-13 | TN | Original correlation plots for run 600102, for comparison to those Fergus has produced. | |

13-Aug-13 | FFW | pixels_ref_HiResLowVt_2.pdf pixels_ref_HiResLowVt_5.pdf pixels_ref_StdLowVt_3.pdf pixels_ref_StdVt_0.pdf pixels_ref_StdVt_1.pdf pixels_ref_StdLowVt_4.pdf pixels_ref_all.pdf | Upgraded versions of the refernce plots with better captions for all 6 sensors. 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:

- Copy RooCherwellLogon.C and RooCherwellAlias.C
- Create or edit .rootrc so it contains the lines:

Code Block |
---|

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

Code Block |
---|

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.

- Standard resistivity ("Std") (Black/sold line).
- Standard resistivity, low Vt ("StdLowVt") (Blue/dashed line).
- 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
