Main Survey: 4 square degrees with MIPS and IRAC in the Constant Viewing Zone (CVZ)

  • 2° x 2° box centered at 17h18m00.0s +59o30m00"
  • ~ 80 seconds/pixel on the sky (MIPS), ~60 seconds/pixel (IRAC)
  • Cirrus: I(100 um) = 1-2 MJy/sr

Verification survey covers ~5% of main survey area with greater depth and redundancy

  • 0.2 square degree strip centered at  17h17m00.0s, +59o45m00s
  • ~400 seconds/pixel on the sky (MIPS), ~600 seconds/pixel (IRAC)

Layout of the Extragalactic Component of the First-Look Survey in the Constant Viewing Zone (CVZ)

The extragalactic component of the FLS was executed in December 2003. The detailed AORs can be viewed in Spot by selecting program ID (pid) 26 or the AOR file linked here.

The layout of the AORs on the sky is shown in the following figures. The red box marks the field center J1718+5930.

IRAC AORs--Main Survey


IRAC Map Layout

Eight AORs cover the field.

MIPS AORs--Main Survey


MIPS Scan Map Layout

Eight AORs cover the field. Each AOR has the following parameters set in Spot:

Each AOR covers roughly 2 degrees by 30 arcminutes with 40 sec per point on the sky (24 micron and 70 micron arrays). The first set is executed and the observations are repeated by the second set with a half-array offset in the starting position. The colors represent 24 micron (green), 70 micron (blue), and 160 micron (peach).

IRAC AORs--Verification Survey

Six AORs cover the field. Three use 12 second exposure times the other 3 AORs use 30 second exposure times.


IRAC Verification Layout

MIPS AORs--Verification Survey

The field is covered 4 times. Each AOR has a slight starting position offset.

Summary

The total time for the extragalactic FLS using these parameters is 62.4 hours. The current AOR file can be downloaded using Spot (this is DDT time, so the PI is Soifer in the ROC pages), or downloaded directly here.
