ATLAS photometry difference images vs. reduced images

[mpgh]

The ATLAS forced photometry feature is very useful. So far it seems that it runs under the assumption that the default settings are used, which would mean difference imaging.

In most cases and in crowded fields this is clearly the preferred option. When dealing with data on sparse fields it would help to change this to reduced images. To illustrate the options available in the requests. The result of the API also contains further values such as

        "radec_epoch_year": null,
        "propermotion_ra": null,
        "propermotion_dec": null,
        "use_reduced": false,

where use reduced true should return photometry und data images without differencing.
