Shower
initiated Light Attenuated to the Space Telescope
|
|
This is a
package of programs written in FORTRAN77 language to simulate both
fluorescence and Cherenkov light produced by extensive air shower
(EAS)
initiated by Ultra High Energy Cosmic Rays (UHECRs) hitting the
atmosphere. The SLAST can be used for various studies of space
telescopes potentials observing the light in the UV region. In few
words, in the SLAST:

SLAST manual
1.Downloading
The
SLAST package is tested on many UNIX/Linux platforms. The current
version is 1.1. 1. download the sources (tar.gz archive) 2. To access always the latest
SLAST version use CVS checkout. To get an access to cvs.in2p3.fr server
please write an e-mail . CVS WEB access is also possible. 2.The
installation
1.unpack
the package (under Linux: tar zxvf slast.v1.r1.compiled.Linux.tar.gz) 2.go
to the SLAST directory 3.run "geninst" (it will take some time to compile the package and to compute all necessary things for the later event generation) Note: First installation
run takes around 10 hours of CPU computations (on 1 GHz clock), if you
want to save your time, download two files lowtran.rwn and slast.hbk (gzipped)
and put them into slast/aux directory. Then you can skip the
installation step. 3.Event
generation
1.edit
datacards/datacard.exp (where "exp" stands for an "experimente you do,
like euso) to set
up number of events, detector parameters, etc (each keyword is
explained) 2.
run "genevt exp" (where again "exp" can be "euso") 4. Output is
PAW Column Wise Ntuple stored at ntuples/euso/events.date (if you run
with datacard.euso, date is the starting job date which makes ntuple
name unique). The ntuple can be opened within the PAW with LREC 4096.
CWN is a compact output with averaged over one Global Time Unit (GTU)
number of photons. |
