AKARI/IRC Pointed Observation Images (Phase 1&2)

Description

The processed images from Infrared Camera (IRC) on board AKARI during Phase 1&2 pointed observations. The field of view of IRC is 10 arcmin and the PSF size is ~5 arcseconds in FWHM. The 9 photometric filters continuously cover the wavelength range from ~2 to ~26 micrometers.

NGC6946 — False colour images from AKARI/IRC observations. From left to right;
NGC 6946 (OBSID 1400620, Blue:Green:Red=3:7:15 micron),
IC 10 (1700216, 3:7:11),
NGC 104 (1700001, 7:11:15),
and North Ecliptic Region (5121023, 2:4:7).
Each image is 10x10 arcmin^2.

Software

Pointed Observation Images (Phase 1 & 2) ver 1.0.1 was produced by processing the raw data with AKARI-IRC Imaging Toolkit ver.150331. Each data package includes the dark data used for processing.

AKARI-IRC Imaging Toolkit [tar.gz (26MB)]

Major improvements of ver.150331 are

better calibration of time-dependent dark and MIR-S flat
better stacking method
better WCS matching

which inrease the S/N and reliability of output images.
Please read README_20150331.txt included in the package and the Data Users Manual (listed below) before using the toolkit.
