UVOT-OC

Source detection and photometry were carried out with DAOPHOT. Calibration was through a custom pipeline using zero points, large-scale sensitivity correction and coincidence loss corrections detailed in the UVOT digest and calibration papers. For a handful of clusters (M34, NGC2287, NGC230, NGC2422, M48), bright stars caused masses of bogus detections. These have been cleaned by matching to the GAIA DR2 catalog. The catalogs are directly ingested from matched multi-filter photometry files. See Siegel et al. (2019) for central wavelengths or the online UVOT Digest for filter curves.

The same photometric catalogs are provided as both CSV and binary FITS tables. In the CSV files, blank spaces indicate non-detections.  In the FITS files, "nan" indicates non-detections and "999999" indicates an empty column.

Data file naming convention:

hlsp_uvot-oc_swift_uvot_<cluster name>_u-uvw1-uvm2-uvw2_v1_cat.fits
hlsp_uvot-oc_swift_uvot_<cluster name>_u-uvw1-uvm2-uvw2_v1_cat.csv

where <cluster name> is the name of the open cluster.
