Real Data DL1 production

Real data will be stored in the IT Container following the structure discussed in the Redmine issue https://forge.in2p3.fr/issues/37938, which includes directories whose name depends on the date. The convention UTC+12, by which days change at noon of the next day, is used at DAQ. For instance, for the data taken in the night 2019_11_23 to 2019_11_24 the selected date would be 2019_11_23 and main directories:

/fefs/aswg/data/real/DL1/20191123/v00 for the default analysis

v00 can take the form of XXX_NN where XXX is the initials of a name and NN a version number (e,g, JLC_01 for the first version of Jose Luis Contreras) when it is an alternative version run by an analysis shifter)

Standard DL1 production for second Crab campaign (January 2020)

Files are in /fefs/aswg/data/real/DL1/<observation_date>/v0.4.3_v00 , produced with lstchain v0.4.3

Standard configuration file was used. You can find it here:

/fefs/aswg/software/virtual_env/ctasoft/cta-lstchain/lstchain/data/lstchain_standard_config.json

Cleaning levels: 6-3

 "tailcut": {
   "picture_thresh":6,
   "boundary_thresh":3,
   "keep_isolated_pixels":false,
   "min_number_picture_neighbors":1

Comments

• DRS4 & CALIB runs from 2020_01_17 and 2020_01_25 are not suitable for producing DRS4 pedestal and calibration files so DRS4 & CALIB runs from other days (2020_01_18 and 2020_01_27 respectively) were used to process the data runs from those days.

• Time calibration file time_calibration.Run1625.0000.hdf5 from 2019_11_24 was used to process all the DL1 files.

MC DL1 production

DL1 MC production to use can be found there for point source gammas:

• /fefs/aswg/data/mc/DL1/20190415/gamma/south_pointing/

Replace gamma with gamma_diffuse, proton or electron.
