Proposed Observation Time
The source list data table will include 2MASS (J, H, and K band), IRAC (3.6, 4.5, 5.8, 8 µm), and MIPS (24 and possibly 70 µm) fluxes in both magnitudes and Janskys.
By using IRAC and MIPS-24, we will be able to identify more young stars via infrared excesses than by using IRAC alone.
Spectral Energy Distributions (SEDs) constructed using IRAC+MIPS (combined with 2MASS) will enable us to discriminate between cluster members and background extragalactic objects.
MIPS-70 will largely reveal the structure of the ISM, though it will also help with identifying cluster members because it will enable us to identify young stars with large mid-IR excesses.
Although data will be obtained at 160 um with MIPS, we do not require it; any ancillary data obtained at MIPS-160 will further enhance our understanding of the interstellar medium in this region.
IRAC Mapping
With IRAC we will detect stars in this region. We will
make a 4 X 5 frame map at 3.6, 4.5, 5.8, and 8.0 microns
with 3 dithers (cycling dither pattern) in the high
dynamic range mode, each exposure 12s. This will cover a
20 x 20 arcmin area which will include both previously
identified targets in this area of the cloud.
The total duration for IRAC will be 1819 seconds.
MIPS Scan Map
With MIPS we will be more sensitive to the ISM than to
stars. We will do a fast scan at 24, 70, 160 microns,
four legs, stepping by half an array each time. This will
cover a 20 arcmin strip through the center of the target,
including most of the IRAC map. Because the MIPS scan
covers a long, thin region compared to the IRAC map, an
ancillary data area will be obtained that covers a larger
portion of the cloud at the three MIPS wavelengths.
The total duration for MIPS will be 1902 seconds.
Total Project Time
The total project time to 3721 sec (62 min).
