Cosmic Microwave Background Software Tools
For the NASA/Advanced Information Science Research Project
Data/Simulation Pipeline
- Simulations
Data Format: COBE Sky Cube at resolution 11
(6,291,456 pixels at 5.25 arcmin!
- Code, Foregrounds -> Sky Representations
- Experimental Simulation (instrument, scan strategy) -> data
- COBE, MAP, Planck
- MAXIMA, BOOMERANG (NA/LDB)
- Interferometers?
- Data Processing
Make Cleaned, Calibrated, Time-Ordered-Data
(From both simulations and experiments)
- Common format
- Handling of Large Datasets
- Pixelization & Pointing
- Cleaning, Calibration, Instrumental Effects
- Data Quality Assurance
- Data Analysis: Extraction/Compression
- "Intermediate Maps"
(a la COBE): contain Noise; use for following analysis
- Power Spectra
- Cosmological Parameters
- Non-Gaussian Statistics?
- "Final Maps"
e.g., Wiener Filtering: extract foregrounds/cosmological signal separately.
- Data Visualization
