Why these photometric measurements are not very precise

Photometric measurements obtained with a wide-field camera are not very precise, for a number of reasons:

Bad plate solution: errors in the astrometric calibration result in misplacement of the photometric aperture. This may create outlier measurements.
Undersampled PSF: star images occupy only a few pixels, so any uncorrected pixel-to-pixel and intra-pixel sensitivity variations affect the measurements more than they would for well-sampled telescopic images in which each star is spread across many pixels.
Differential atmospheric extinction across the image: an airmass-dependent magnitude zero-point correction is applied, but it is not perfect.
Color-dependent (second-order) extinction: a star's brightness measured relative to the comparison stars in the field is elevation-dependent if the star's color differs from the average color of the comparison stars.
Blending with nearby stars in crowded fields affects the measurements differently depending on the aperture size, which is adjusted for each image individually based on the seeing and focus quality.
Position-dependent PSF: the same star may fall closer to the image center in one field and farther from it in another, so a different fraction of its PSF is covered by the aperture even when the same aperture is used to measure both images. Field-to-field and camera-to-camera calibration is therefore an issue, and its magnitude differs from source to source.
Chromatic aberration: many wide-field lenses suffer from it, leaving extremely red stars out of focus while the focus is optimal for average-colored stars.
Clouds, if present, dramatically degrade the quality of the photometry across the entire image.

In practice, expect a photometric uncertainty of ~0.1 mag, or somewhat better in favorable conditions.

The intended use of these data is a quick check of the current state of a source (flaring or quiescent) - not precise photometry.
