+
+## Benchmarks
+
+### 1. Framework Comparison
+Compares Astropy baseline (1 thread & 4 threads) vs Cutana (1 worker & 4 workers):
+```bash
+python run_framework_comparison.py --size small
+python run_framework_comparison.py --size big
+python run_framework_comparison.py --test # Only 12k-1tile-4channel
+```
+
+**Scenarios:**
+- 1 tile, 4 FITS, 50k sources
+- 8 tiles, 4 FITS/tile, 1k sources (8k total)
+- 4 tiles, 1 FITS/tile, 50k sources (12.5k per tile)
+
+**Output:** `results/framework_comparison_*.json`, `results/framework_comparison_summary_*.csv`
+
+### 2. Memory Profiling
+Tracks memory usage over time for 1 tile scenario:
+```bash
+python run_memory_profile.py --size small
+python run_memory_profile.py --test # Use 12k-1tile-4channel
+```
+
+**Profiles:**
+- Astropy baseline (4 threads) - best baseline performance
+- Cutana 1 worker
+- Cutana 4 workers
+
+**Output:** `figures/memory_profile_*.png`, `results/memory_profile_stats_*.json`
+
+### 3. Thread Scaling Study
+Analyzes scaling from 1-8 workers (tests: 1, 2, 4, 6, 8):
+```bash
+python run_scaling_study.py --size small
+python run_scaling_study.py --test # Use 100k-1tile-4channel
+```
+
+**Metrics:**
+- Runtime vs workers
+- Throughput vs workers
+- Speedup factor
+- Parallel efficiency
+
+**Output:** `figures/scaling_study_*.png`, `results/scaling_metrics_*.json`
+
+### 4. LaTeX Values
+Generates LaTeX macros from benchmark results:
+```bash
+python create_latex_values.py
+```
+
+**Output:** `latex/latex_values.tex`, `latex/benchmark_summary.txt`
+
+## Configuration
+
+### Configuration File: `benchmark_config.toml`
+
+All benchmark parameters are now centrally configured in `benchmark_config.toml`:
+
+```toml
+[astropy_baseline]
+target_resolution = 256 # Target resolution for resizing (pixels)
+apply_flux_conversion = true # Enable flux conversion (AB magnitude)
+interpolation = "bilinear" # Interpolation: nearest, bilinear, bicubic, biquadratic
+zeropoint_keyword = "MAGZERO" # FITS header keyword for AB zeropoint
+
+[cutana]
+target_resolution = 256 # Target resolution for cutouts
+N_batch_cutout_process = 1000 # Batch size for processing
+output_format = "zarr" # Output format: zarr or fits
+data_type = "uint8" # Data type: uint8, uint16, int16, float32, float64
+normalisation_method = "none" # Normalization method
+interpolation = "bilinear" # Interpolation method
+apply_flux_conversion = true # Enable flux conversion
+
+[framework_comparison]
+warmup_cache = true # Warm up FITS cache before benchmarks
+warmup_size = 1000 # Number of sources for cache warmup
+
+[plots]
+dpi = 300 # Resolution for saved plots
+figure_width = 12 # Figure width in inches
+figure_height = 6 # Figure height in inches
+```
+
+**Edit this file to customize benchmark parameters without modifying code.**
+
+## HPC Benchmarking Features
+
+✅ **Cache warming** - Pre-loads FITS headers before measurements
+✅ **Progress tracking** - Shows warmup progress every 10 sources, benchmark progress every 1000 sources
+✅ **Memory management** - Explicitly closes files to avoid buildup
+✅ **Realistic I/O** - Simulates HPC scenario with cached metadata
+✅ **Multiple runs** - Scales tests across different worker counts
+✅ **Detailed logging** - INFO level logs show real-time progress and statistics
+
+## Catalogues
+
+### Small (for testing/development)
+- **50k-1tile-4channel**: 50k sources, 1 tile, 4 FITS files
+- **1k-8tiles-4channel**: ~8k sources (1k/tile), 8 tiles, 4 FITS/tile
+- **50k-4tiles-1channel**: 50k sources (~12.5k/tile), 4 tiles, 1 FITS/tile
+
+### Big (for paper)
+Same structure as small, larger source counts for final results.
+
+## Expected Runtimes
+
+| Mode | Time | Description |
+|------|------|-------------|
+| Test | ~3-5 min | Only 50k-1tile-4channel |
+| Small | ~30-60 min | All 3 scenarios, small catalogues (50k sources each) |
+| Big | ~2-4 hrs | All 3 scenarios, big catalogues (larger datasets) |
+
+Individual scripts:
+- Framework comparison: ~20-40 min (3 scenarios × 3 methods, 50k sources each)
+- Memory profiling: ~10-15 min (1 scenario, 3 methods, 50k sources)
+- Scaling study: ~30-45 min (1 scenario, 5 worker counts, 50k sources)
+- LaTeX generation: <1 min
+
+## For the Paper
+
+After running benchmarks:
+
+1. **Plots:** Copy from `figures/` folder:
+ - `memory_profile_*.png`
+ - `scaling_study_*.png`
+
+2. **LaTeX macros:** Include `latex/latex_values.tex` in paper preamble:
+ ```latex
+ \input{path/to/latex_values.tex}
+ ```
+
+3. **Use in text:**
+ ```latex
+ Cutana achieves \cutanaFourRate{} cutouts per second with 4 workers,
+ representing a \speedupFour{}× speedup over the Astropy baseline.
+ ```
+
+## Troubleshooting
+
+**Missing catalogues:**
+```
+ERROR: Catalogue not found: paper_scripts/catalogues/small/100k-1tile-4channel.csv
+```
+→ Create catalogues or check path. Test catalogues should be in `catalogues/small/`.
+
+**Memory errors:**
+→ Use `--test` mode or smaller catalogues first.
+
+**Long runtime:**
+→ Use `--size small` for faster testing.
+
+**FITS file paths:**
+→ Ensure FITS files are in `paper_scripts/data/` or update paths in catalogues.
+
+## Enhanced Baseline Implementation
+
+### Astropy Baseline (`astropy_baseline.py`)
+
+The enhanced Astropy baseline now includes a **complete processing pipeline** for fair comparison.
+
+**Thread Configurations:**
+- Benchmarks run with explicit 1-thread and 4-thread configurations for direct comparison
+- Thread limits are set to match Cutana's per-process behavior
+- Uses OMP_NUM_THREADS, MKL_NUM_THREADS, etc. to control threading in numpy/scipy operations
+
+#### Processing Steps:
+1. **FITS Loading**: Memory-mapped loading with file caching
+2. **Cutout Extraction**: Using `astropy.nddata.Cutout2D`
+3. **Resizing**: Target resolution scaling with skimage (same as Cutana)
+4. **Flux Conversion**: AB magnitude to Jansky conversion (configurable)
+5. **Normalization**: 0-1 range normalization
+6. **FITS Writing**: Individual FITS files per cutout (cleaned up after benchmark)
+
+#### Timing Breakdown:
+All benchmarks now generate **detailed timing breakdown charts** showing:
+- Time spent in each processing step
+- Percentage of total time per step
+- Comparison between Astropy baseline (1t, 4t) and Cutana (1w, 4w)
+
+**Output charts:**
+- `figures/astropy_1t_timing_*.png` - Astropy 1-thread baseline timing breakdowns
+- `figures/astropy_4t_timing_*.png` - Astropy 4-thread baseline timing breakdowns
+- `figures/cutana_1w_timing_*.png` - Cutana 1 worker timing breakdowns
+- `figures/cutana_4w_timing_*.png` - Cutana 4 workers timing breakdowns
+
+This represents a **realistic research workflow** with all necessary processing steps, making the comparison fair and comprehensive.
+

+Framework comparison benchmark for Cutana paper.
+
+Compares runtime and throughput (cutouts/second) for:
+- Astropy baseline with 1 thread
+- Astropy baseline with 4 threads
+- Cutana with 1 worker
+- Cutana with 4 workers
+
+Across three scenarios:
+1. 1 tile, 4 FITS, 50k sources
+2. 8 tiles, 4 FITS per tile, 1k sources per tile (~8k total)
+3. 4 tiles, 1 FITS per tile, 12.5k sources per tile (50k total)
+
+HPC Benchmarking Practices:
+- Warm-up runs before actual measurements
+- Cache warming for realistic I/O performance
+- Multiple runs with median timing

+End-to-end tests for raw cutout extraction with StreamingOrchestrator.
+
+This module tests the combination of:
+- do_only_cutout_extraction=True (raw cutouts without resizing/normalization)
+- StreamingOrchestrator batch-by-batch processing
+
+Test Setup:
+- Creates mock FITS files with known values
+- Uses StreamingOrchestrator to process sources in batches
+- Validates that output cutouts preserve original data values
+
+Key validations:
+- Raw cutouts maintain original data type (float32)
+- No resizing is applied (cutout size matches extraction region)
+- No normalization is applied (values match input)
+- Streaming batch processing works correctly with raw mode
+- Both sync and async streaming modes work with raw cutout extraction
