The exhaustive analysis of the available transition lines of H^13^COOCH_3_ has led to the assignment of 7457 spectral lines by means of a global fit of 45 parameters, using the Rho-Axis Method (RAM) and the BELGI-Cs code, with a resulting unitless standard deviation of 0.57. Over 1600 lines are included for the first time in the fit. In addition, the line strengths of spectral lines are also calculated using the most recent experimental measurement of the electric dipole moment. In conclusion, the present study represents a notable improvement with respect to previous H^13^COOCH_3_ spectral analyses. Therefore, the better accuracy of the present analysis may help the future identification of new H^13^COOCH_3_ lines in the interstellar and circumstellar media, and may contribute to decrease some of the spectral confusion due to these species in astronomical surveys.2010ApJS..190..315Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/190/315CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/500/1109 : Rotational spectrum of HCOO^13^CH_3_ (Carvajal+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/190/315https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/190/315http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/190/315https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/190/315https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/190/315http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/190/315GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefault
