ChiantiPy version 0.10.0 has been released

[Ken Dere]

The updated version is available on the ChiantiPy github page and PyPI.

Changes from 0.9.5 to 0.10.0
============================

The Karzas and Latter (1965) bound-free gaunt factors in the CHIANTI database have been corrected as of CHIANTI version 10.  This effects the calculation of the free-bound continuum.  The continuum.freeBound method has been updated to uses these new data.

The freeBound and the freeFree methods now have 2 new keyword variables:  **includeAbund** and **includeIoneq**.  Their initial values are True so that elemental abundance and the ionization equilibrium appropriate to the ion is included the the output spectrum.

The freeBoundEmiss is removed as it has become redundant

A new continuum method, freeBoundLossMao includes the radiative-recombination (free-bound) loss rate as calculatd by Mao et al. (2017)

a bug in the inherited method base._IntensityRatio() was corrected.

Dear Ken,
I am interested in computing the emission at radio/mm wavelengths of a relatively low
temperature (~1500-2000K) atmosphere dominated by H- and H2- continuum opacity where most
of the electrons come from ionized metals. Can CHIANTI do this?

thanks
raghvendra

Hi raghvendra

The CHIANTI database has no infomation about H- or H2 so it will be help you in this case.

I can not even guess what to recommend.

best regards,

When I import ChiantiPy.core as ch,the Ipython give me this information. I don't know what induce this problem.

I already have chianti.ip in the path: /usr/CHIANTI/0ChiantiData/ip/

Thanks for any anwser!

Hi 

have you set the environmental variable XUVTOP to the top of the CHIANTI database?  The path is a different variable.

it looks like XUVTOP should be set to /usr/CHIANTI/0ChiantiData, or something like that

Ken

[Mingyue Hao]

Hi Ken Dere

Before I using it,I have set the variable like this export XUVTOP=$/usr/CHIANTI/0ChiantiData.

And I write this variable to the /etc/profile,

but it sames didn't work and I got the wrong information

[Ken Dere]

Hi 

If you do

> printenv XUVTOP

do you get the correct directory

i.e., if you cd to XUVTOP are you in the right place?

you may need to open a new terminal so that the new XUVTOP gets picked up by reading /etc/profile

Ken

[Mingyue Hao]

Hi Ken 

After I set the right environmental variable,I have tried import ChiantPy.core as ch,IPython give me the information below.

If  I do printenv XUVTOP, the terminal give me:  /usr/CHIANTI/chiantidata.

I cd to /usr/CHIANTI/chiantidata/continuum,but there is no such file klgfb.dat and all I have is 

klgfb_1.dat,klgfb_2.dat,klgfb_3.dat,klgfb_4.dat,klgfb_5.dat,klgfb_6.dat.

In the latest version of CHIANTI, that file was removed as it replaced by a the other files that you see.

I am working to fix this, hopefully soon

Ken
