Questions Generated from Use Cases for U1, U2, U14, A1, A5.

1. Can we assume CALDB is locally installed on the user's machine? (could be large).
2. Source files? What format should these be in and which programs need to read/write them?
3. Binning services which tools need binning and how should this be achieved?
   

1. Does U1 really need to know anything about Pulsar phase or should this cut be done with U2?
2. Is U2 expected to do binning?
3. Can U1 and U2 be made the same?  (Bob: not inclined to do that ? U2 must support many plotting options & isexpected to read and write FITS files ? U1 may not even touch the FITS files - depending on implementation.
   
4. Do we really need U1 to run on Users machine?
5. A1. What intermediate data products need to be writeable? (e.g., Exposure matrix, residuals map, Npred, Likelihood map)
   
6. U14. (DRM gen) GRB coordinate questions:

• should we add the option to specify GRB location in sky coordinates?
• Will another tool specify GRB location in detector coordinates?
• Does U14 calculate it for him/her?
• Do we want U14 to calculate orbital average of burst location?
• Do we want U14 to calculate orbital average of instrument response?
• One minute of duration corresponds to about 4 degree in angle. Is it small enough to ignore scanning motion of the instrument?
