cds-question@unistra.frbl-lacertae-objectsquasarsx-ray-sourcespolarimetryvisible-astronomyastronomical-modelsredshiftedX-ray polarization should provide new probes of magnetic field geometry and acceleration physics near the base of blazar jets, but near-future missions will have limited sensitivity. We thus use existing lower energy data and X-ray variability measurements in the context of a basic synchro-Compton model to predict the X-ray polarization level and the probability of detection success for individual sources, listing the most attractive candidates for an Imaging X-ray Polarimetry Explorer campaign. We find that, as expected, several high-peak blazars such as Mrk 421 can be easily measured in 100ks exposures. Most low-peak sources should only be accessible to triggered campaigns during bright flares. Surprisingly, a few intermediate peak sources can have anomalously high X-ray polarization and thus are attractive targets.2019ApJ...880...29Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/880/29CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/swift : Swift Master Catalog (HEASARC, 2004-)VII/274 : The Roma BZCAT - 5th edition (Massaro+, 2015)J/AJ/144/105 : MOJAVE.
