#   then for each source:
#     <source number>
#     <latitude deg> <longitude deg> <model layer index, 1 = lowest layer>
#     <number of tracers emitted by this source>
#     <frequency> <offset> <duration> <end_sol>

# Timing line
#   frequency : interval between the starts of two events (sols). Must be a
#               multiple of the physics timestep and larger than duration.
#   offset    : start of the first event, in sols after the run starts. Must
#               be a multiple of the physics timestep. The fractional part
#               sets the time of day on the reference meridian (0 deg E);
#               local solar time at the source = 24*frac(offset) + lon/15.
#   duration  : length of each event (sols). May end inside a physics step;
#               the last step is then weighted so flux x duration is exact.
#   end_sol   : no event starts at or after this sol (exclusive). Must not
#               cut the last event short.
#
# A single continuous release is one event: offset + frequency >= end_sol.
# A pulsed release is a short duration repeated every "frequency" sols.
# The run.log records label a source "continuous" or "pulsed" by that rule.
# At the first physics call the EMISSIONS_PLAN records in run.log give the
# number of events, active seconds and mass each source should emit, over
# its whole schedule and within this run; EMISSIONS_ASSERT_PASS and
# EMISSIONS_BUDGET at the last call must match the in-run numbers.
# Example below: physics step = 1/192 sol (day_step=960, iphysiq=5).
