Timing Review March 15, 2017

This review will examine the current observation overheads and speed-performance trades. These affect both:

  • survey efficiency
  • data delivery time (and thus time from observation to event detection)

It is understood that we do not have final, or in some cases even preliminary results, but the purpose of this meeting is to focus attention on these important issues and make sure that we are moving in the right direction and will arrive in time. All timing issues are up for discussion including but not limited to command processing overheads, readout time, repointing, control loops (guide, focus), filter exchanges, FITS file writing and data transport to IPAC.

Guidelines

Speakers are asked to present: * Design values * Describe current/planned measurement methods * Data on current performance (if available). * Speed-performance trades (eg. read noise vs. read speed; slew time vs. settling accuracy) * Plans for further tests and improvements. * Timeline for further work
