The Data Processing Department of the Astro Space Center of the P.N. Lebedev Physical Institute (Moscow, Russia) has been developing a software project 'Astro Space Locator' (ASL for Windows) as an alternative package to AIPS and DIFMAP. We tested AIPS against ASL for an extremely marginal data set consisting of a single baseline from Hobart to VLBI Space Observatory Program (VSOP) (VS041). The Penticton data quality analysis (DQA) found occasional fringes on this baseline, but AIPS failed. ASL managed to match the DQA fringes and can apply these to the data.
