This page is far from being complete. While I give an introduction to my students, I try to write down a few notes, hoping that it can serve as a small introduction and help future students.

Analysis Steps

callisto

what is done?

calculation of calibration constants, extraction of signal, calibration of data

macro

Mars/fact/analysis/callisto.C

input

sequence file, rawdata (files found with information in sequence file

output

YYYYMMDD_SSS-calibration.root (plots), YYYYMMDD_FFF_C.root (one per run)

star

what is done?

image cleaning, calculation of image parameter

macro

Mars/fact/analysis/star.C

input

sequence file, callisto output

output

YYYYMMDD_SSS-images.root (plots), YYYYMMDD_FFF_I.root (one per run)

ganymed

what is done?

background suppression, calculation of excess(, energy reconstruction)

macro

Mars/fact/analysis/ganymed.C

input

dataset file, star output (_I.root files)

output

name-analysis.root (result, eventlist after cuts, plots), name-summary.root (event list before cuts)

lightcurve

what is done?

calculation of excess rate

macro

Mars/fact/analysis/lightcurve.C

input

several datasets or information from DB

additional information

sequence

a sequence of runs, consisting of: pedestal run, light pulser run, one or more data runs

dataset

a collection of data runs

FFF

file number (starts with 0 every night

SSS

sequence number (number of first run in sequence)

technical information

how to start a macro

go to Mars directory
start root
.x path/macro.C ("with maybe some variable", 2)

set root environment

source /pathtoroot/bin/thisroot.sh
