Our sample consists of 81 variables with accurate periods and optical (VI) magnitudes from the OGLE survey, covering various subtypes of pulsators (BL Herculis, W Virginis, and RV Tauri). We generate light-curve templates using high-quality I-band data in the LMC from OGLE and K_s_-band data in the Galactic bulge from VISTA Variables in Via Lactea survey (2010NewA...15..433M) and use them to obtain robust mean magnitudes. We derive period-luminosity (P-L) relations in the near-infrared and Period-Wesenheit (P-W) relations by combining optical and near-infrared data. Our P-L and P-W relations are consistent with published work when excluding long-period RV Tauris. We find that Pop II Cepheids and RR Lyraes follow the same P-L relations in the LMC. Therefore, we use trigonometric parallax from the Gaia DR1 (Cat. I/337) for VY Pyx and the Hubble Space Telescope parallaxes for {kappa} Pav and 5 RR Lyrae variables to obtain an absolute calibration of the Galactic K_s_-band P-L relation, resulting in a distance modulus to the LMC of {mu}_LMC_=18.54+/-0.08 mag. We update the mean magnitudes of Pop II Cepheids in Galactic globular clusters using our light-curve templates and obtain distance estimates to those systems, anchored to a precise late-type eclipsing binary distance to the LMC. We find that the distances to these globular clusters based on Pop II Cepheids are consistent (within 2{sigma}) with estimates based on the M_V_-[Fe/H] relation for horizontal branch stars.2017AJ....153..154Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/154CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)J/AcA/49/223 : BVI photometry of OGLE LMC Cepheids (Udalski+, 1999)J/ApJS/142/71 : BVRI observations of LMC Cepheids (Sebo+, 2002)J/AJ/128/2239 : JHKs photometry of 92 LMC Cepheids (Persson+, 2004)J/MNRAS/370/1979 : JHKs photometry of T2Cs in globular clustersJ/AcA/58/293 : Type-II and anomalous Cepheids in LMC (Soszynski+, 2008)J/MNRAS/397/933 : LMC type II Cepheids JHKs magnitudes (Matsunaga+, 2009)J/AcA/61/285 : VI light curves of Galactic Bulge CepheidsJ/ApJ/743/76 : Spitzer photometry of LMC Cepheids (Scowcroft+, 2011)J/MNRAS/424/1807 : VISTA Magellanic Cloud Survey.
