In addition, it 'might' be that you also need more than one plasma frequency.  However, it has been a long time since I ran spin polarized optical calculation, so I don't remember for sure.

I think there were plamsa frequencies from running both "x joint -up" and "x joint -dn" from a spin polarized calculation:

I think it was possible to have multiple plasma frequencies from "x joint -up" (case.outputjointup) and "x joint -dn" (case.outputjointdn) based on:

After using addjoint-updn, I think I might have had to combine all plasma frequencies from case.outputjointup and case.outputjointdn in case.inkram for "x kram" to run without error.

According to the user's guide, at the 5th line of abc.inkram a value for each column in abc.injoint should be provided. Two values are probably not enough because the code fails when it reads this 5th line.

Hi,
Please, here is abc.inkram:

0.1    Gamma: broadening of interband spectrum
0.0    energy shift (scissors operator)
1      add intraband contributions? yes/no: 1/0
4.149   plasma frequencies  (from joint, opt 6)
0.20 0.2   Gammas for Drude terms

        *Subject:* [Wien] Calculating x kram with intra-band contribution

        Dear all,
        I am trying to calculate optical properties for a
        spin-polarized half-metal. x optic, x joint ( with both
        options 6 & 4 as specified) all ran smoothly. Without
        intra-band i.e 0 in line 3 of inkram, x kram executed smoothly
        also. However, when intra-band contribution is added by using
        '1' as input in line  3 of inkram, x kram failed.
        Please, I need assistance to overcome this.
        Regards
        CMI Okoye
