Pricing

The nature of the tasks and, therefore, their progress can be very different, all pricing are based on individual agreements. As a guide we list some tasks below:

Individual projects:

  • Tlusty Stellar Atmosphere Model calculations

    • Such tasks are computationally intensive, therefore we apply a general flat rate of 5 EUR/day/CPU-thread. Only exceptions are the Tlusty models with H and He composition, which are 3 EUR/model. For reference, the estimated calculation times with Tlusty are:
      • 20-30 minutes with H,He,C,N,O composition
      • 6-12 hours with the first 30 elements (14 explicit non-LTE, assuming no convergence problems).
    • For large samples or lengthy calculations please inquire about special rates.
  • Spectroscopic fits with XTgrid and spectral classifications

    • These fits employ Tlusty models, therefore the same 5 EUR/day/CPU-thread rate applies. For reference, the estimated calculation times of XTgrid fits with 40-60 iterations and a single CPU-thread are:
      • 1-2 days with H,He,C,N,O composition
      • 2-3 weeks with the first 30 elements (14 explicit non-LTE; assuming normal convergence rate; depends on the observed data and cluster load as well).
      XTgrid is ready for parallel computations which provide a 30%-90% speed-up of the iterations depending on the actual type of iterations and the number of CPU-threads reserved for the project.
  • Animation and Media Content (Blender, Gimp)

    • Such tasks depend on the type and complexity of the requested material. Prices are upon agreement, please inquire.
  • Service Observing (visitor mode)

    • We request a full travel reimbursement (all travel, accommodation, observatory residence expenses) plus 100 EUR/day and travel insurance.
  • You name a task, like: code designing or optimizing, consulting, proposal writing, etc.

    • These tasks are rated at 5 EUR/hour and we apply a tracking system with 15 minutes ticketing to measure our time spent on a project. Describe the problem, if we can help, we will agree on something.

Collaborative partnerships for stellar atmosphere model calculations or spectroscopic fits:

  • "Round collaboration"

    • Long-term (annual) collaboration in spectroscopic projects including up to 8 CPU threads for a flat rate of 360 EUR/month.
  • "Half-round collaboration"

    • Medium-term (6 months) collaboration in spectroscopic projects including up to 8 CPU threads for a flat rate of 640 EUR/month.
  • "Quarter-round collaboration"

    • Short-term (3 months) collaboration in spectroscopic projects including up to 8 CPU threads for a flat rate of 920 EUR/month.
