I'm working with some data and I have some values named fluxmag0fluxmag0
and fluxmag0errfluxmag0err
that should correspond to the zero point values and error in flux units.
The values are around 10**13$10^{13}$ for fluxmag0fluxmag0
and 10^9$10^9$ for fluxmag0errfluxmag0err
I need to have the zero point error in magnitude units. If I take 2.5log10(fluxmag0err)$2.5\log_{10}(\mathrm{fluxmag0err})$ the values are hudgehuge so I suppose it's not the way to compute this.
How can I convert these values in terms of magnitudes ?
Thanks a lot in advance for your help
