# NOTE: THIS IS A NEW VERSION OF THE OBSERVATION SCRIPT!
# CHAGLELOG: 
#   Oct 2024: replace focussing algorithm (T. Fatkhullin)
#             At the night start the first focussing run
#             uses of two-step algorithm:
#               1) rough focus astimation along full season-to-season
#                  focus range (as it was implemented in the old obs. script)
#               2) precise focussing along narrow range computed from
#                  previous rough estimation
#             Next focussing runs compute range from the current focus value.
#             (new function 'focustel_new')
#
#  May 2025: rewrite detection of running this script process (T. Fatkhullin)
#            (use of '-c' commandline option for 'pgrep' command)
