Some facts on new delivery system use
• Total number (69)• Over 1.5 requests per working day in Jan• Responding within a 3 day period generally• Main queries/confusions
• Very small requests (all parameters exactly the same as user’s observation)
• Very wide selection – changed approach. Previously asked for re-submission, now make judgement on file/restrict size and go straight to delivery

User queries, example correspondence• M. Ajello – (using old files). Scaling question,
discrepancy between blank sky and user observation at high energies. User observation highly SP contaminated. Query closed.
• M. Wezgowiec – repeated queries. Files constructed, tailored to user requirements. Query closed.
• M. Gitti – repeated queries. Required longer exposure than received. Tailored files. Query closed.
• (Other): software available, how to scale bkg, good feedback, asking about SW/LW

Outstanding issues
• Ghosting – bad flags in/good flags out spatially
• Add example current blank sky files to web form so requests not necessarily needed
• Implement some minor changes after internal user comments regarding web page text
• Other output to add to response page: exposure weighted nH from list component files
