MiaplPy run_07_mintpy_ifgram_correction error: plot_num_triplet_with_nonzero_integer_ambiguity of unwrap_error_phase_closure.py: `bins` must be positive, when an integer"

[falkamelung]

Although the 2015-2026 data work

minsarApp.bash 19.456:19.615,-103.666:-103.573 qColima --start-date 20150701 --end-date 20151231 --flight-dir asc,desc --platform S1 --no-mintpy --miaplpy

gives an error:

The data data:

ls qColimaSenA49/secondarys/
20150817  20151028  20151227
(minsar) //login3/scratch/05861/tg851601/qColimaSenA49[1135] get_reference_date
20150724

This seems to happen only for this set of data. It works when I add one date (20160201)

minsarApp.bash 19.456:19.615,-103.666:-103.573 q2Colima --start-date 20150701 --end-date 20160501 --flight-dir asc --platform S1 --no-mintpy --miaplpy^C
(minsar) //login3/scratch/05861/tg851601/q2ColimaSenA49[1127] ls secondarys/
20150817  20151028  20151227  20160201
get_reference_date
20150724

Also this work wit slightly different dates:

minsarApp.bash 19.456:19.615,-103.666:-103.573 q3Colima --start-date 20150701 --end-date 20150101 --flight-dir asc --platform S1 --no-mintpy --miaplpy^C
