spectrum and mspectrum error

Sandino Estrada Dorado <s.es...@irya.unam.mx>: Apr 01 03:38PM -0600 Hello,   I recently reinstalled ChiantiPy and now when I try to calculate a synthetic spectrum I got the error message:   KeyError: 'ne_1'     I have checked the installation and the path and the files, and nothing.   The line I try to run is:     ch.mspectrum(temperature=temp, eDensity=dens, wavelength=wvl, filter= (chfilters.gaussian, 0.01), minAbund=minimal, abundance='ISM_Cloudy', doContinuum=1, em=dem)     Where ISM_Cloudy is a tested abundance I use.   Anyone could have an idea about to solve this problem?     Thank you in advance.   Sandino.

Hi all,

I discovered that the problem was with the masterlist_ions.pkl file that is packaged with version 11.0.1 of the Chianti database.

To fix this I moved that file aside (renamed to masterlist_ions_old.pkl) and in python did:

ionInfo = chio.masterListInfo(force=True)

(where I previously did import ChiantiPy.tools.io as chio)

That recreates the masterlist_ions.pkl file using the masterlist.ions file as input. After that I didn't run into the problem with the KeyError for ionInfo['ne_1']

I think this is a bug with the Chianti database distribution and needs to be fixed.

Hello Jonathan,

I got a mail from Ken with the following instructions:

to fix this

> from ChiantiPy.tools import io

> io.masterListInfo(force = True)

this will rebuild the masterlist_ions.pkl file.

this will take a while

Anyone having problems like this, should do the same.

And It solve the problem.

Greetings

Sandino
