In general, the specified position of an observation in the plain text
ROC will be at the center of any requested map. Observers should take
map center offsets into consideration when searching for possible
duplications. The mapped area columns in the ROC indicate the approximate
area on the sky and do not imply that depth coverage is the same
throughout the map.
Observations tagged as GENERIC can 'move' up to 2 degrees. See the Spitzer Observer's Manual for more
information about Generic targets.
A note about Guaranteed Time Observations and the title Principal
Investigator (PI): All Spitzer Programs must have a Principal
Investigator. Many of the Spitzer GTOs are collaborating on various
observing programs, contributing some of their time allocation to form
Shared Time Programs. There are over two dozen of these Shared Time
Programs within the ROC. In the case of a Shared Time Program the PI need
not be a GTO and in a few cases a non-GTO was chosen to be PI of the
Program.
There are duplications within the ROC. In some cases these are
due to requested return visits to targets for temporal studies. In other
cases the investigators split up observations into multiple AORs to work
around the maximum time duration per AOR restrictions. Also, a few Shared
Time Programs return to some targets to increase integration times or for
temporal studies. These are not considered conflicting duplications since
one of the contributing GTOs in the Shared Time Program is PI of the
apparent duplicate observation.
