Target name: G333.6-0.2 2. Coordinates: 16:22:09.6 -50:06:00 (J2000) Fujiyoshi et al. (2005, MNRAS, 356, 801) 3. Brightness: 10 Jy arcsec^-2 @ 24.5 um (assuming F_20/F_10 ~ 2) 5 Jy arcsec^-2 @ 12.5 um (Fujiyoshi et al. 1998) 4. Filter: Q24.5, N12.4 5. Time: According to the COMICS web page, the total observing time is given by t_tot = (SNR*NEFD/flux)^2 / (efficiency) * (N_beam)^2/(2*N_on_source) As it is an extended source, it should be chopped and nodded off-chip so N_beam = 4 and N_on_source = 2. We aim for SNR of at least 20 for the Q-band imaging and 100 for N-band. According to the various tables on the COMICS web pages the sensitivity (NEFD) = 7900 mJy arcsec^-2 for the N24.5-filter and its efficiency at that wavelength is 25 % (ADD mode). Therefore, t_tot = (20*7900/10000)^2 / (0.25) * (4)^2/(2*2) ~ 67 minutes For the N12.4-filter, NEFD = 680 mJy arcsec^-2 and efficiency is 60 %. So for an SNR of 100, t_tot = (100*680/5000)^2 / (0.60) * (4)^2/(2*2) ~ 21 minutes 6. Standard: gamma-Cru [F_IRAS_25 = 221 Jy, F_IRAS_12 = 865 Jy; 12:31:09.96 -57:06:47.6 J2000 (SIMBAD)] 7. Chop throw: 60" 8. Chop off-position: 60" in the south-west direction (PA = 225 degrees). 9. Position angles: To offset at the above position, according to the COMICS position angle page, we should set Inst_PA = -Obj_PA = 0 deg Chop_PA = -135 deg 10. Priority: 1. Q24.5 2. N12.4 11.
