DAN-TOF is the provisional name for the generalization approach to SANS data reduction. New SANS instruments are multi-detector by design and, by default, time-of-flight (TOF) instruments or have a TOF option.

• data format if HDF5 (NEXUS)
• ND number of detectors; ND is number of synchronically saved detectors with identical normalization (time or monitor), number of TOF channels NTOF ,
• NTOF (number of TOF channels) could be re-binned for all detectors identically (linearly, progressivelly, …)
• NR (number of repetitions) could correspond to:
  • just repetitions (will be added later)
  • real-time experiment: all frames will be treated separately
  • could correspond to different experimental modes, like for polarised neutrons (++, +-, -+, –)

HDF adress examples:

• /raw_data_1/detector_1/counts
• /entry1/SANS/detector/counts

HDF arrays examples:

1. single detector VECTOR:
   • [dimX x dimY]
   • [dimY x dimX]
2. single detector MATRIX:
   • [dimX][dimY]
   • [dimY][dimX]
3. single detector VECTOR / repeated NR:
   • [NR][dimX x dimY]
   • [NR][dimY x dimX]
   • [dimX x dimY][NR]
   • [dimY x dimX][NR]
4. single detector MATRIX / repeated NR:
   • [NR][dimX][dimY]
   • [NR][dimY][dimX]
   • [dimX][dimY][NR]
   • [dimY][dimX][NR]
5. single detector VECTOR / repeated NR / TOF frames NTOF:
   • [NR][dimX x dimY][NTOF]
   • [NR][dimY x dimX][NTOF]
6. single detector MATRIX / repeated NR:
   • [NR][dimX][dimY][NTOF]
   • [NR][dimY][dimX][NTOF]

Single Detector Image / NON-TOF:

• general [1][128][256][1]
• non-tof [1][128][256]
• simplest [128][256]

Suggested to support formats:

• [NR][dimX][dimY][NTOF]
