        • 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)

        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)

        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.

        Towards the muon calibration paper
        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
