QDOAS Analysis Windows properties : Output page
For each cross-section defined in the Molecules page, this page proposes to select the analysis results to save in the ASCII output file(s). Columns are enabled only if the Analysis button is checked in the Output page of Projects Properties. QDOAS calculates and saves vertical columns if an AMF dependency has been selected in the Molecules page. The Residuals column gives the possibility to specify a value for the residual column amount of the selected species in the reference spectrum. In the output file, slant columns and vertical columns (and their respective errors) can be divided by a scaling factor using Slnt Fact and Vrt Fact edit controls. In the output file, the title of columns with the retrieval results always starts with the name of the analysis window. Slant columns are indicated by SlCol, standard deviations by SlErr, vertical columns by VCol, air mass factors AMF, etc... For example, if the application contains two analysis windows (no2 and o3), no2.slcol(o3) and o3.slcol(no2) refer to the column titles for respectively the slant columns of O3 in the no2 window and NO2 in the o3 fitting window. The Annex of the Software User manual presents examples of output generated by QDOAS.
