[Pw_forum] "recipe" for isostm_plot

[Christoph Wolf]

Dear all,

I was wondering if someone could share his or her experience with getting
nice iso-STM images from pwscf that would allow me to go beyond trial and
error...

- what are good stm tip heights (example03 has <1 A)
- how to estimate a reasonable bias (to me it seems that 0.1...1 V work OK)

and the hardest nut to crack:

- how to get a reasonable isovalue=0.00005 by looking at charge density
maps at certain isolevels (?)...

Any help is welcome, I read through chdens_module.f90 to understand how it
works but I am yet to discover how to make the results "pretty"!

Best wishes and a nice Monday to you all,

Chris
