UKIRT Microlensing Survey Figures

Here we include figures created by the UKIRT Microlensing Team that describe various aspects of the UKIRT microlensing survey, which are intended for public consumption and dissemination. We simply request that appropriate citations and credit are given if these are used in talks and presentations.

Observational Coverage Maps

Figure 1 - Distribution of target fields for the 2015 (northern Galactic bulge) and 2016 (southern Galactic bulge) UKIRT microlensing surveys.

Also included in the right panel is the survey superstamp area (pink) for K2's Campaign 9 (K2C9), which can be found in the K2C9 white paper (cf. Figure 7): Henderson, C. B., et al. (2016) PASP, 128, 124401.


Figure 2 - Distribution of target fields for the 2017 UKIRT microlensing survey, either shown with the WFIRST microlensing survey target field region (left panel) or overlaid on the KS-band extinction map of: Gonzalez, O. A., et al. (2012) A&A, 543, A13 (right panel). For all green fields, the primary filter is H-band, for which there is 1 epoch per night, and the secondary filter is KS-band, for which there is 1 epoch every 5 nights. For all red fields, the primary filter is KS-band, for which there are 2 epochs per night, and the secondary filter is H-band, for which there is 1 epoch every 3 nights. For all blue fields, the primary filter is KS-band, for which there are 3 epochs per night, and the secondary filter is H-band, for which there is 1 epoch every 3 nights. The green fields with positive Galactic latitude are designated as northern Galactic bulge fields. All blue fields are designated as central Galactic bulge fields. Both red fields and the green fields with negative Galactic latitude are designated as southern Galactic bulge fields.
