Description 21cm absorption spectra for the 44 MACH lines of sight. Data is published in fits table format, including LSR velocity ('v_lsr'), optical depth at 21cm ('tau_hi') and the estimated per-channel 1-sigma uncertainty ('sigma_tau_hi'). The Galactic coordinates for each target are included in the file name.

The corresponding emission spectra from the Effelsberg-Bonn HI Survey (EBHIS; Winkel et al. 2016) used in the analysis (i.e., spectra for the 40 off-positions surrounding each target source) are also included for reference. The positions of the off-positions are illustrated in the reference figure ("tb_ebhis_layout.pdf"), wherein each position number corresponds to the table column name index in each datafile (e.g., position 12 corresponds with the "tb_ebhis_12" spectrum).
