10:00 Status of MC Simulations

Speakers: Johan Bregeon (CNRS IN2P3 LUPM), Markus Gaug (UAB Barcelona, Spain), Michael Prouza (Institute of Physics - Prague)

AtmoSim_update_JB.pdf

• Piping corsika output into more than 3 simtel_array is not efficient because Corsika allocates only 1 CPU core, while 3 simtel_array's (on 3 cores each) are waiting for input basically idle. Moreover, simtel_array allocates ~1 GB of memory, cannot run more than 3 because of that.
• We will soon call for a meeting in cta-wp-ccf-atmosim@cta-observatory.org, to organize the required MODTRAN tables by Johan.
• The -DEXTRACLOUD option seems to be an efficient solution for the clouds only.
• A full proton simulation setup for CTC  is available by Stan Stefanik, he will provide all his input to Johan
• Johan asks for a person running basic tests on first output. That person should ask Konrad for help (but also Johan is avaiable)

Wednesday 4 October

09:30 → 11:20 Common issues

09:30 Status of EoIs and plans for In-kind-contributions

Speaker: Markus Gaug (UAB Barcelona, Spain)

Array calibration:

Instrumentation:   

Illuminator:    full IKC from INAF, but need to be updated for current number of devices

UAV:    should be part of a larger IKC, but cannot be incorporated in INAF IKC.

Methods and Software:

Should be a global package, led by some coordinating institute, but the rest are "small" contributions, Before, the relation between A&S WG and CTAO must be legally clarified. (Might be an IKC from CTAC) 

 

Atmospheric Calibration:

Site Characterization:

a) Acquired data that can be "transferred" to CTAO wihtout any IKC

b) Certain data products want to be an IKC: ARCADE, existing photometer not, but perhaps a new one for CTA-N

c) Spftware not included so far in EoI

Dynamic Scheduling:

ASC+ Ceilometer: IKC of AS-CR, EoI needs be updated for ASC w.r.t. dyn. scheduling

Software: Should at least be led by AS-CR

 

Atmospheric Corrections:

FRAM+CTC: EoI of AS-CR, check whether 3 are included in EoI

LIDAR: 2 EoI's, but one inofficial from CEILAP

Software: Can AS-CR lead this part ?? (discuss with Michael Prouza)

 

Weather monitoring:

CTA-Spain:   full IKC for CTA-N + software for CTA-S

Hadrware for CTA-S: directly pruchase by CTAO ???

 

UVScope: IKC of ASTRI, should one UVScope be included for CTA-N? (Support of the Illuminator)

 

10:00 CTA-N infrastructure for CCF equipment

Speaker: Carla Crovari

CTAN Infrastructure for CCF equipment.pdf

• Markus will send an updated excel spreadsheet for infrastructure questions to the corresponding parties. 
• CTA-N phase 2 will probably need 3-4 years (e.g. the technical building probably complete in 2021)
• Infrastructure is probably ready in Q2 of 2019
• CTAO will produce all foundations at once
• There is a parallel session dedicated to INFRA @ CTA-N on Tuesday afternoon, during the general meeting, also a visit to ORM is foreseen
• Dusan comments on the need to have soon reliable power and internet connection in CTA-S, also maintenance of instruments is difficult
• Plans are to use intially a power generator, however nothing major is expected to happen before 1-1.5 years from now.

Speakers: Maria Concetta Maccarone (IASF-Palermo/INAF, Istituto di Astrofisica Spaziale e Fisica Cosmica di Palermo/Istituto Nazionale di Astrofisica), Markus Gaug (UAB Barcelona, Spain)

1. Introduction  - ready
2. Review of muon spectra and fluxes: ready
3. Review of the method: ready

4 & 5: Merge, shorten and generalize:  Markus

6: Intensity fitting: Update with log-likelihood (Alison's thesis):  Alison

6.2, 6.3, 6.4: Shorten and move to Section 5: Markus

7: Systematic Uncertainties:  core of the paper, perhaps shorten a bit, if possible: Markus

8: Simulations: core of the paper

• keep an introduction mentionning the CORSIKA flags, and used site (atmosphere)
• remove all further group-specific information
• redo all simulations with Prob3b, and ctapipe
• ask Gernot about status for Prob3b (updates from telescopes such that MC corresponds to current designs): ready for LST, SST-1M, ASTRI, ongoing for GCT, FlashCam, NectarCam, MST structure and MST-SC.
• Common plots for all telescopes:
  • Bias and Resolution of all parameters used to derive the muon efficiency: as a function of muon energy, and as a function of mirror degradation  (perhaps also as a function of impact parameter and inclination angle, have to see how big they are).
  • Gaussianity of distributions
  • Linearity of distributions
  • Further plots will be suggested by Alison in a list at the beginning of this section

9: Muon flagging in camera server: Cettina

• too much ASTRI focused
• needs to get updated with latest results (shown at this meeting)
• include speed of algorithms
• include Q-factor (perhaps as function of muon energy?)
• include additional data rate obtained if the flagging is active

10: Trigger strategies and expected rates: Markus

• need updated MC simulations

11: Discussion: Markus

• rewrite according to results obtained from simulations
• table 6 can stay (slightly updated)
• remove all internal new requirements

12: Conclusions: all

• write at the end, same for abstract

Schedules:

• full text w/o chapter 8: 27/11/2017
• full simulation chain with ctapipe including plots: end of 2017

Further topics:

• Discuss effect of large square camera for MST (effects of inclination angle), plots from Steve Fegan
• Appendix revisited formulae for 2M telescopes: will be revisited by Alison and Teresa
• Technical comparison of algorithm for generic telescope: might go in a separate paper, Alison to decide
