Reporting Photometric Error...

Hi Folks:

I'm rather new at this, so bear with me.  :-)

When submitting observations to the AID, I'm wondering what error to report. When I do photometric reduction on an image using VPhot I get the following:

Target      Mag       Err      Std      Err(SNR)      SNR      Sky

TX Per      10.198  0.224   0.224   0.003          398       7

Now, up to this point I've been reporting (using this instance as an example) an error of 0.224, but in this example that seems an awful large error to me. When I took an estimate of AF And the other day and had a similar error I attributed it to a faint star and an underexposed image (for the star brightness I was taking). But this is not that way with TX Per. I got a good image. Its not faint, its sharp, its good. I don't think the magnitude error should be 0.224m.

Is this the error I should be reporting, or am I doing this totally wrong?

Thanks, guys!
