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 v0.4.4 production for 2019 and 2020 data (edited: March 6, 2020)
Files are in /fefs/aswg/data/real/DL1/<observation_date>/v0.4.4_v00
, produced with lstchain v0.4.4
Note: these v0.4.4 data are for the first time processed with the intended LocalPeakWindowSum, same as MC.
Standard lstchain configuration file was used: cta-lstchain/lstchain/data/lstchain_standard_config.json
. Hence these cleaning settings were applied:
"tailcut": { "picture_thresh":6, "boundary_thresh":3, "keep_isolated_pixels":false, "min_number_picture_neighbors":1 }
Find all the details about which runs where analyzed in the tables below (DL1 Analysis logbook).
Additional 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.
- By default (from January 2020 on), ucts time-stamps
"timestamps_pointing":"ucts"
are used to interpolate pointing coordinates.
- However for Nov 2019 data, dragon-based time-stamps were used for the interpolation:
"timestamps_pointing":"dragon"
- Corrected new drive log files were used for Nov 2019:
/fefs/aswg/scripts-osa/corrected_drive_logs_Nov19/

Standard DL1 v0.4.3 production for 2019 and 2020 data (edited: January 2020)
Files are in /fefs/aswg/data/real/DL1/<observation_date>/v0.4.3_v00
, produced with lstchain v0.4.3
Standard lstchain 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 }
