Sat 01-04-2017 11:39:55:: WARNING : All Gaussians were flagged for the following islands:
Island #1 (x=0, y=2707)
Island #4 (x=17, y=1505)
Island #21 (x=100, y=724)
Island #227 (x=1436, y=2902)
Island #269 (x=1735, y=1227)
Please check these islands. If they are valid islands and
should be fit, try adjusting the flagging options (use
show_fit with "ch0_flagged=True" to see the flagged Gaussians)
or enabling the wavelet module (with "atrous_do=True").
To include empty islands in output source catalogs, set
incl_empty=True in the write_catalog task.
