Production preparation - missing items

[GernotMaier]

Collect missing items related to a full production configuration:

• calculate of required number of events (e.g., use Abelardo's equation n_showers = 2 ×105 × exp [3.9781*(cos(ZD) – 1)] (total per pointing, in whatever number of files). --> Set the number of showers and number of runs in the generated production grid #2201
• Compare between our estimates and Abelardo's suggestions for core scatter radius and energy ranges.
• Clarify with Abelardo the minimum photons and minimum p.e. setting - see simulation models, simulation model parameter setting
• Note Abelardo suggests reducing the the shower-reuse parameter to 10 (at least for diffuse gammas). It's probably not a bad idea after this round of trigger optimisations. Derive re-use factor from trigger shower distribution #2205
• Settle on the maximum energy, current plots on slack do not show that. Production generation: max energy of simulations #2204
• Scaling of number of events with zenith angle Add zenith-angle scaling mode for showers_per_run in production grid generation #2207 Add zenith-angle-dependent scaling of showers_per_run for job duration control #2206
• Trigger threshold (asum_threshold) is suggested to be reduced by 10% (from 230 used in LSTProd2). simulation model. simulation model parameter setting
• Update mirror_degraded_reflection to 0.784 simulation models
• Define the 1 node/deg^2 list of pointings Allow to define production grids using a grid density parameter #2213
• Clarify with Abelardo (most likely in a call) the need for such a dense grid.
• Should we switch to the curved atmosphere CORSIKA above 65 deg? It is done automatically in simtools actually, no?
• setup of production configuration repositories - see here
• check / fix the usage of the corsika limit tables to set the ranges in the production grid.
• ...

Should we switch to the curved atmosphere CORSIKA above 65 deg? It is done automatically in simtools actually, no?

simtools-simulate-prod has a command line parameter, e.g. --curved_atmosphere_min_zenith_angle 60. deg to switch from flat to curved.

defaults.py has to default value set to:

# Minimum zenith angle (degrees) above which CORSIKA uses a curved-atmosphere binary.
CURVED_ATMOSPHERE_MIN_ZENITH_ANGLE_DEG = 65
