Data for "A Near-Infrared Extinction and Reddening Map Towards the Galactic Bulge Using UKIRT"

Data for $A_{K_S}$ extinction and $E(H-K_S)$ reddening maps towards the Galactic Bulge using the United Kingdom Infrared Telescope (UKIRT) with $2^\prime \times 2^\prime$ resolution. The maps provide the following header information: l: Galactic longitude ($l$; deg) b: Galactic latitude ($b$; deg) aks: $A_{K_S}$ extinction (mag) aks_err_up: Difference between the 84th and 50th percentiles of $A_{K_S}$ (mag) aks_err_low: Difference between the 50th and 16th percentiles of $A_{K_S}$ (mag) ehks: $E(H-K_S)$ redenning (mag) ehks_err: Square root of the variance in $E(H-K_S)$ (mag) Flag: Flag=0 represents standard reporting of the $A_{K_S}$ extinction. Flag=1 represents a field with exponential fit parameter $B<0.2$, and thus is reported solely as a lower limit on the $A_{K_S}$ extinction (see Section 3.6 of Zelakiewicz et al. 2025).
