AKARI/IRC Pointed Observation Images from Phase 1 and 2 (ISAS/JAXA, 2015) ================================================================================ AKARI/IRC Pointed Observation Images (Phase 1 and 2) Egusa F., Usui F., Murata K., Yamamura I., Onaka T., Yamashita T., on behalf of the AKARI team ================================================================================ ADC_Keywords: Photometry, infrared Mission_Name: AKARI Description: This data package contains processed images taken with the InfraRed Camera (IRC) on board AKARI (ASTRO-F) during Phase 1 and 2 when the instruments were cooled by the liquid Helium. AKARI/IRC performed about 4000 (~3000 photometric and ~1000 spectroscopic) pointed observations during these phases. The observations were designed and carried out in the science programmes, namely one of "Large Area Survey (LS)", "Mission Programme (MP)", "Open Time Programme (OT)", or "Calibration/Director's time (DT)". The first ~40 observations during the performance verification phase (PV Phase) are excluded from this release due to the low quality of MIR-S flat frames. Each data set corresponds to a single pointed observation and includes a readme file, a process log, processed and calibrated images, and corresponding dark frames. A summary for all the data sets is also available. Please refer to Egusa et al. (2015) or IRC Data Users Manual for details of data processing, calibration and caveats of the data.

The name of a stacked image is represented by a combination of target-ID (TID), subID (subID), observed band (band) with extension as "TID_subID_band_long.fits" stored in "stacked_IM/". Neighbor dark frames for MIR-S and -L are stored as "dark/ndark[S/L].d0n11.fits".
