We present a systematical analysis of the Chandra observations of 53 nearbyhighly-inclined (i>60 degree) disk galaxies to study the coronae around them.This sample covers a broad range of galaxy properties: e.g., about three ordersof magnitude in the SFR and more than two orders of magnitude in the stellarmass. The Chandra observations of the diffuse soft X-ray emission from 20 ofthese galaxies are presented for the first time. The data are reduced in auniform manner, including the excision/subtraction of both resolved andunresolved stellar contributions. Various coronal properties, such as the scaleheight and luminosity, are characterized for all the sample galaxies. Forgalaxies with high enough counting statistics, we also examine the thermal andchemical states of the coronal gas. We note on galaxies with distinctmulti-wavelength characteristics which may affect the coronal properties. Theuniformly processed images, spectra, and brightness profiles, as well as theinferred hot gas parameters, form a large X-ray database for studying thecoronae around nearby disk galaxies. We also discuss various complicationswhich may cause biases to this database and their possible corrections oreffects, such as the uncertainty in the thermal and chemical states of hot gas,the different galactic disk inclination angles, the presence of AGN, and thecontribution of the emission from charge exchange at interfaces between hot andcool gases. Results from a detailed correlation analysis are presented in acompanion paper, to gain a more comprehensive statistical understanding of theorigin of galactic coronae.
