Pipeline

Processing stages:

• Preprocess
  • Downsample
  • Normalization
  • Remove baseline
• RFI mitigation
  • Manually zap
  • Skewness-Kurtosis filter
  • Zero-DM matched filter
  • KadaneF filter
  • Mask filter
• Dedispersion
• Matched filtering
• Clustering
• Candidate plotting

transientx_fil

TransientX includes a full processing pipeline for transient detection, as shown in the diagram below. The pipeline reads data from SIGPROC filterbank files or PSRFITS files (using options such as --wts, --scloffs, --zero_off, and --psrfits) in data chunks. The length of each chunk can be configured using the -l option. The pipeline produces candidate plots in PNG format and generates a candidate list.

replot_fil

The replot_fil tool reprocesses the candidates generated by transientx_fil, removing duplicate and bad candidates based on multiple criteria, and can generate archive files for further analysis.
