Isochrone Fitting of Galactic Globular Clusters -- VI. High-latitude Clusters NGC5024 (M53), NGC5053, NGC5272 (M3), NGC5466, and NGC7099 (M30)

We fit various colour-magnitude diagrams (CMDs) of the high-latitude Galactic globular clusters NGC,5024 (M53), NGC,5053, NGC,5272 (M3), NGC,5466, and NGC,7099 (M30) by isochrones from the Dartmouth Stellar Evolution Database and Bag of Stellar Tracks and Isochrones for $\alpha$-enrichment [$\alpha$/Fe]$=+0.4$. For the CMDs, we use data sets from {\it Hubble Space Telescope}, {\it Gaia}, and other sources utilizing, at least, 25 photometric filters for each cluster. We obtain the following characteristics with their statistic uncertainties for NGC,5024, NGC,5053, NGC,5272, NGC,5466, and NGC,7099, respectively: metallicities [Fe/H]$=-1.93\pm 0.02$, $-2.08\pm 0.03$, $-1.60\pm 0.02$, $-1.95\pm 0.02$, and $-2.07\pm 0.04$ dex with their systematic uncertainty 0.1 dex; ages $13.00\pm 0.11$, $12.70\pm 0.11$, $11.63\pm 0.07$, $12.15\pm 0.11$, and $12.80\pm 0.17$ Gyr with their systematic uncertainty 0.8 Gyr; distances (systematic uncertainty added) $18.22\pm 0.06\pm 0.60$, $16.99\pm 0.06\pm 0.56$, $10.08\pm 0.04\pm 0.33$, $15.59\pm 0.03\pm 0.51$, and $8.29\pm 0.03\pm 0.27$ kpc; reddenings $E(B-V)=0.023\pm 0.004$, $0.017\pm 0.004$, $0.023\pm 0.004$, $0.023\pm 0.003$, and $0.045\pm 0.002$ mag with their systematic uncertainty 0.01 mag; extinctions $A_{\mathrm{V}}=0.08\pm 0.01$, $0.06\pm 0.01$, $0.08\pm 0.01$, $0.08\pm 0.01$, and $0.16\pm 0.01$ mag with their systematic uncertainty 0.03 mag, which suggest the total Galactic extinction $A_{\mathrm{V}}=0.08$ across the whole Galactic dust to extragalactic objects at the North Galactic pole. The horizontal branch morphology difference of these clusters is explained by their different metallicity, age, mass-loss efficiency, and loss of low-mass members in the evolution of the core-collapse cluster NGC,7099 and loose clusters NGC,5053 and NGC,5466.
