Sequencer Site SIRTF IOC Activity c. 2002

CAID: MIPS-135 Title: SED of a Circumstellar Disk
 
System: MIPS Principal: jstansberry Deputy: psmith
Objective:  
Evaluate  AOT -- MIPS SED

Confirm cross calibration between SED and
photometry mode observations of a source.
 
Description:
Acquire normal SED observations of a 
moderately
bright (S/N ~ 3 in 10 second DCE). The same 
source
should also be observed in photometry mode 
to
allow a 1st order confirmation of the
cross-calibration between the two modes.
 
Day:   81.9777777777781 Suggested Order:   V800
 
Must be preceded by these activities (list by CAID):   MIPS-300, MIPS-275
 
Place in Schedule:   After aperture door open After CTA/instrument cool down and all other instrument testing is complete. Location of MIPS SED aperture must be completed.
 
Priority:   Necessary


Conditions

Maximum telescope temperature: 12 K
 
Minimum telescope temperature: 5.5 K
 
Should activity be repeated if focus changes?   No     Repeat if focus changes by 0 mm
 
Maximum absolute pointing uncertainty: 3 arcsec (1 sigma radial)
 
Maximum precision offset uncertainty: 1 arcsec  (1 sigma radial)

Data Volume (uncompressed): 59 Mbits
 
List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): AOR. 2 cycles, 10s DCEs.
 
List Analysis tools required (downlink):   Standard pipeline system and standard data analysis tools required.

Outcome


Estimate of data turn around:   8 hours
 
Description: SED spectrum of circumstellar disk produced by pipeline.
 
Can proceed in parallel with other activity: No
 
Must outcome be confirmed before next activity: No
 
Method of Confirmation:   Data analysis
 
 
Success criteria:
 
Contingency plan:  Revisit SED flux calibration scheme if SED fluxes and 70um photometric points are not in fairly good agreement.
