Wrong spectral index when concatenating two skymodel

[flomertens]

I tried to concatenate two sky model with the following code:

import lsmtool
s1 = lsmtool.load('catalog.skymodel')
s2 = lsmtool.load('Ateam_lowres.skymodel')
lsmtool.operations.concatenate.concatenate(s1, s2)

this used to work fine with earlier version of lsmtool but with version 1.4.9, I get wrong spectral index and ref frequency in the resulting skymodel.

For example, previously (output_1-4-7.skymodel):

1858.9+2503, POINT, Main, 18:58:54.2496, 25.03.00.684, 1.2851, 0.0, 0.0, 0.0, 60000000.0, [-0.4473, 0.0], 0.0, 0.0, 0.0

now (output_1-4-9.skymodel):

1858.9+2503, POINT, Main, 18:58:54.2496, 25.03.00.684, 1.2851, 0.0, 0.0, 0.0, 999999.0, [-0.4473, 1e+20], 0.0, 0.0, 0.0

catalog.skymodel.txt Ateam_lowres.skymodel.txt output_1-4-7.skymodel.txt output_1-4-9.skymodel.txt

Thanks for reporting this issue (and including all the info to make it easy to reproduce!). It should be fixed now on the current master, and we will make a new release soon (likely v1.4.10) that includes the fixes.
