- time series data with stationary noise and signals
- statistical concepts (moments, median, higher moments)
- template placement, mismatch, ROC curve
- sensitivity computational cost analysis
- parallelization with a cluster using condor

- find the right parameter in data with noise
- noise realization, statistical properties of noise, plot different realizations of noise and properties there-of (moments, rms)
- properties of simple signal without noise, plot different sample systems, i.e.
- work with different files, store these in SCM
- adding signal + noise, plot various realizations
- learn to use
**prober**, our small black box program computing a scalar result based upon input time series and parameter point - start to learn how prober results vary w.r.t. varying input parameters of injected signal while probing the same parameter point
- plot/document result findings, e.g. how large may the mismatch between injection and probe parameter may become, what about weak signals?
- develop strategy to find signal with prober if signal parameters are unknown
- with this strategy perform multiple injections to arrive at mismatch graphs (with and without signals) and ROC curve to evaluate template bank properties
- repeat with coarser and finer template bank

- plot
- plot always means a graphical output with proper labels, title

- C programming language
- scripting language (Python is particularly useful)
- SCM (software configuration management) tool (git)
- basic statistical working knowledge (mean. variance, higher moments), time series analysis

- using debugging, profiling and performance monitoring tools
- construct a Makefile
- writing of programs to solve particular problems
- creating data type precision problems
- discovering and handle IO problems
- program optimization
- software configuration management
- download and compile the LAL software
- parallel programming skills, such as GPU programming, MPI and OpenMP

- the usage of condor to manage jobs
- generating DAG-man jobs

- generate a random and a stochastic template bank
- generate a mismatch statistic of a random, a stochastic and an optimized template bank, what is the meaning of it
- generate a roc curve, explain the consequences in terms of data analysis resources and sensitivity
- find an injected signal
- find correlation between different signals
