#  Sourced by submit.sh and run_slurm.sh. The OGGM version, patch, container
#  and sample data come from the v5 gdirs config, so that the runs always

# Per-glacier dynamic melt_f calibration (DYN_CALIB=1 ./submit.sh ...): the
# calibration runs start in DYN_YS, and must match Hugonnet within
# DYN_ERR_FACTOR x its error (0.2, as oggm_prepro). Up to 20 iterations of a
# DYN_YS -> 2025 run per glacier, hence the longer time limit.

# Minimum max-step of melt_f between two calibration iterations
# (melt_f_max_step_length_minimum). OGGM's own step formula has a bug: it
# uses |melt_f_min - melt_f_initial| / maxiter instead of the distance to the
# farther bound, so on its own melt_f can only move ~+-3.5 from 5. We don't
# patch OGGM for this: the step is max(that formula, this minimum), so 0.3
# reproduces the intended step for melt_f_initial ~5 and maxiter 40 (12/40).
# It acts as a prior on how far melt_f may move from its static value:
# 0.1 = OGGM's current behaviour (the *_dynbug runs), 0.3 = the *_dyn runs.
