Hubble Heritage observations of NGC 281 ----- Submission 1 (Wed May 18 15:59:20 GMT 2005) ----- I know the visits will schedule. Hubble Heritage Observations of NGC 281 The Hubble Heritage team will use a single pointing of ACS WFC to obtain F435W, F555W, F658N, and F814W images of NGC 281 as part of a public release image.
Observing NGC 281 with 4 filters. The constraints on the orient were made to allow the large globule and stream of dust to be included in the image, but to remove the 10 the magnitude star at the NE corner of the field. We are not concerned with cosmetic effects that the proximity of this star may cause. We have decided not to include shorter exposures as a consistent S/N is more valuable than artifacts that can be later removed. 0 false 0.0 false false false false false SUPPORTED ISM DARK CLOUD J2000 00 00 0.0000 +00 00 0.00 J2000 POS-TARG DITHER 3.011 LINE false false 2 85.28 ACS-WFC-DITHER-LINE 1 false POS-TARG DITHER DITHER 2 3.011 ACS-WFC-DITHER-LINE false false 0.145 2 85.28 POS-TARG ACS-WFC-DITHER-LINE 47.23 2 true /data/norbert1/williamj/work/OP-cache/10713-v01.xml (Tic-Visit :proposal-id 10713 :visit-id "01" :proposal-version -1 :trans-version "20050502" :date "25-Jul-2005 08:27:32.0" :trans-errors '(:WARNINGS 0 :ERRORS 0 :HEALTH-AND-SAFETY 0 :FATAL-ERRORS 0 :CONTINUABLE-FATALS 0) :number-of-orbits 3 :saa-model "27" :si-bright-earth-limb-angle 20.0 :data-volume 2842240 :tdrss-contact-duration 0 :coron NIL ) (Tic-Obset :proposal-id 10713 :visit-id "01" :obset-id "01" :pcs-mode "FGS" ) (Tic-Orbit :proposal-id 10713 :visit-id "01" :orbit-number 1 :pcs-time 367 :si-vis-utilization 3144 :al-overhead-at-end 0 :internal-dur-at-end 0 :dark-offset NIL :dark-utilization 0 :max-dark-utilization 1920 :low-sky "N" :pcs-visibility 3517 :pcs-gap 0 ) (Tic-Orbit :proposal-id 10713 :visit-id "01" :orbit-number 2 :pcs-time 367 :si-vis-utilization 3110 :al-overhead-at-end 0 :internal-dur-at-end 0 :dark-offset NIL :dark-utilization 0 :max-dark-utilization 1920 :low-sky "N" :pcs-visibility 3517 :pcs-gap 0 ) (Tic-Orbit :proposal-id 10713 :visit-id "01" :orbit-number 3 :pcs-time 367 :si-vis-utilization 3126 :al-overhead-at-end 0 :internal-dur-at-end 349 :dark-offset NIL :dark-utilization 0 :max-dark-utilization 1920 :low-sky "N" :pcs-visibility 3517 :pcs-gap 0 ) false 3 0 /var/tmp/OPVisit30892.xml
