(NanoAOD · Run2016H · SinglePhoton)
We help researchers turn raw NanoAOD ROOT files into clean, analysis-ready tables (CSV / slim ROOT) with reproducible logs and optional Certified JSON labeling (Certified / Alternative by run–lumi).
You keep your brain for physics — we handle the plumbing.
If your dataset is close (other NanoAOD eras / other CMS channels), ask — we may already support it.
Scope (v1): /SinglePhoton/Run2016H-UL2016 (CMS Open Data, NanoAOD).
The scope can be expanded later (all NanoAOD → CMSSW pipelines → other CERN domains) once the first workflow is proven.
If you’re unsure what’s inside your files or how hard the extraction will be, start here.
€49–€79 (up to ~2 hours)
Deliverables:
If you like the result → we move to the full task.
You provide a short technical brief (what objects, what columns, what selection).
We reply with scope + deliverables + timeline.
For complex tasks, we split into 2–4 stages.
Each stage is paid after you receive the result for that stage.
Typical stages:
€49–€79
Best for sanity checks and pilot runs. Validate your branch list before committing to full processing.
Output: branch-map + 1 demo file (slim ROOT/CSV) + QC note
€150–€300
Includes: 1 TTree, agreed selection, one fixed column schema, 1 revision round
Output: flat CSV (or slim ROOT) + minimal QC note + reproducible run command(s)
€400–€900
Includes: multiple input files, consistent schema, Certified JSON labeling (Orthodox/Heretic), reproducible scripts/macros, QC + basic plots
Output: dataset bundle + logs + quick-read documentation

We’re a team of engineering-driven enthusiasts with roots in web development since 2006. Over time, we shifted toward harder, high-friction problems where discipline, reproducibility, and systematic thinking matter more than “quick hacks”.
Along the way, we started exploring fundamental physics and quickly learned how painful it is to work with raw datasets. We built a strict extraction workflow (see the Demo) and now offer it to anyone who needs clean, reliable data outputs.
CMS_2016H_photons_flat_v1 — “Minimal Photon Flat Table”
A ready-to-use event-level CSV extracted from CMS Open Data (Run2016H SinglePhoton), flattened to a compact schema:
The dataset contains over 1.2 million events, each represented as a single row with event-level identifiers and leading-photon observables extracted from NanoAOD.extraction.
The compressed archive size is 50.3 MB and expands to 132.4 MB after
