cds-question@unistra.frnovaeapparent-magnitudePre-outburst and post-outburst light curves and post-outburst eclipse timings are analyzed to measure any period (P) change related to nova CI Aql's outburst of early 2000 and a mean post-outburst dP/dt, which then lead to estimates of the accreting component's rate of mass (M) change and its overall outburst-related change of mass over roughly a decade of observations. We apply a recently developed procedure for unified analysis of three timing-related data types (light curves, radial velocities, and eclipse timings), although with only light curves and timings in this case. Fits to the data are reasonably good without need for a disk in the light-curve model, although the disk certainly exists and has an important role in our post-outburst mass flow computations. Initial experiments showed that, although there seems to be an accretion hot spot, it has essentially no effect on derived outburst-related {Delta}P or on post-outburst dP/dt. Use of atomic time (HJED) in place of HJD also has essentially nil effect on {Delta}P and dP/dt. We find {Delta}P consistently negative in various types of solutions, although at best only marginally significant statistically in any one experiment. Pre-outburst HJD_0_ and P results are given, as are post-outburst HJD_0_, P, and dP/dt, with light curves and eclipse times as joint input, and also with only eclipse time input. Post-outburst dP/dt is negative at about 2.4{sigma}. Explicit formulae for mass transfer rates and epoch-to-epoch mass change are developed and applied. A known offset in the magnitude zero point for 1991-1994 is corrected.2014ApJ...795....8Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/795/8CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/140/34 : Classification of nova light curves (Strope+, 2010)J/A+A/544/A26 : CI Aql spectra during 2000 outburst (Iijima, 2012)J/PASP/125/126 : Light curve of CR Boo over 1990-2012 (Honeycutt+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/795/8https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/795/8http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/795/8https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/795/8https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/795/8http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/795/8GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJ/795/8/table1CI Aql MMO Light Curve DatarecnoRecord number assigned by the VizieR team.
