Data Management

Working on developing and updating science codes for Community Pipeline, whose goal is to analyze data taken by community users with DECam camera. Here is a list of topics I worked with:

  • Implementation of multiple overscan fitting techniques used for basic detrending and calibration codes for Community pipeline
  • Removal of outliers pixels due to bright stars in creation of twilight skyflats.
  • Benchmarking of masking code used in DESDM (to determine bottlenecks).
  • Data quality checks of CP1 data challenge datasets (which are mosaic)
  • Investigation of some SExtractor object parameters such as FWHM for Blanco Mosaic2 data
