The latest galactic merger simulations are finding an unexpected increase of star formation in extended tidal debris, with 20 - 50% of the systems star formation rate occurring in these regions. We see this observationally in massive clusters forming in the Tadpole galaxy, occupying 30% of the system's star formation rate. At the same time, clusters suffer high rates of disruption, dispersing their material into the diffuse light of the tail and mixing with old stars drawn from the parent galaxies. We intend to break our tidal tails into their composite populations using HST and ground-based Gemini imaging. Our existing WFPC2 VI-band and HI data indicate clusters prefer to live in regions of high HI kinetic energy and low shear. However, analysis is limited to population studies, as the lack of UB-band data prevents us from age or mass estimates, permitting only a shallow understanding of the relationship between local HI properties and star clusters. Additionally, while the high resolution of HST is necessary for identifying and studying star clusters, it is unsuitable for the sensitive imaging needed to study the faint, diffuse tails. Our proposed 11 orbits of WFC3/ACS UB-band imaging will allow for precise age and mass measurements of our star clusters, while ground-based imaging searches the diffuse light for the cluster destruction history. In this manner, we will determine the present and past history of star formation in tidal tails, and the HI densities and kinematics required for cluster formation. ------------------------------------------------------------------------------------ Observations Description 15083( 5) - 13-Dec-2018 15:41:59 - [ 2] ------------------------ Our program involves U/F336W and B/F438W WFC3 imaging of tidal tails in which WFPC2 V/I imaging data is already available. We are interested in photometry of faint point- and marginally-resolved sources over the entire WFC3 FOV, and we are requesting a 4 point dither pattern (where possible- see parallels below) for each filter to properly sample the PSF in our final, combined images. We do not need to cover the chip gap, as long as the ORIENT ranges (below) are OK. We needed to make sure the chip gap does not cover area where stars clusters were detected in the WFPC2 data. Our original request was to have 1.5 orbits in U, and 0.5 orbit in B; however, with the preference for a 4-dither pattern, and avoiding any observing inefficiencies with <360s exposures, our best possible observing strategy appears to be 1.3 orbits (U), the remainder of the 2nd orbit in B. Although we are interested in the highest possible S/N in our observations, we have left a few x 10s left in each orbit to allow for maximum flexibility in scheduling. Should these cuts be unnecessary, we would like to bump up the F336W observation exposure times as much as is possible to fill the orbit, while still allow for maximum schedulability VIsits: Five of our visits are two-orbits in length, and make use of WFC3 alone, with no parallels. In those cases, we have adopted a 4 point DITHER-BOX pattern to providue the best possible PSF sampling. We do NOT need to fill in the chip gap for these observations. For the 2 single-orbit visits of NGC2992/3, we have requersted parallel observations. We have found that there appears to be no effieicnt way to get 4 equal exposures in the primary camera *and* have 4 equal exposures in the parallel obervations. For these visits I have created a manual (using POS-TARGs) 4 point dither pattern, but with unequal exposures, and unequal FLASH values (reason I did not use set DITHER-BOX pattern) Thus we have used a 3 point sub-pixel dithering pattern to get the bast sampling for these visits only. FLASH: We also require a post-FLASH for all WFC3 images due to the relatively short individual exposures in both of these blue filters. We used the ETC to look at the expected range of background values assuming the lowest (faintest) possible sky background for each target (our objects span a wide range in ecliptic latitudes), and assuming no Earthshine or zodiacal light. This way we have a conservative estimate for the needed FLASH to reach 12 e-/pixel in the WFC3 images. Similar, used same methodology for the ACS images - FLASH normally not required, but the shorter exposures (400s) in F435W yield a lowest possible 19 e-/pixel, so we have added FLASH=1.0 to those. However, under normal observations perahsp we do not need to add this? Roll Angles: Our ORIENT ranges are based on the requirement to cover the WFPC2 footprint from previous observations of these galaxies, but we have found we have many months of available scheduling for each object, with the exception of the NGC 2992/3 observations (with the parallels) where we have perhaps 1-2 weeks of schedulable time due to the much more restricted roll angle requests. ------------------------------------------------------------------------------------ 15083( 5) - 13-Dec-2018 15:41:59 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC-1487E GALAXY, TIDAL TAIL RA=03H55M48.9834S +/- 0.1", J2000 V = 24.02 +/- 0.2 DEC=-42D20'54.17" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the NED database. ------------------------------------------------------------------------------------------------------------------------------------ 2 NGC-1487W GALAXY, TIDAL TAIL RA=03H55M30.7615S +/- 0.1", J2000 V = 24.57 +/- 0.2 DEC=-42D22'40.47" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the NED database. ------------------------------------------------------------------------------------------------------------------------------------ 5 NGC-2992 GALAXY, TIDAL TAIL RA=09H45M41.5061S +/- 0.1", J2000 V = 23.47 +/- 0.2 DEC=-14D17'29.71" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the NED database. ------------------------------------------------------------------------------------------------------------------------------------ 18 NGC-3256W GALAXY, TIDAL TAIL RA=10H27M35.9798S +/- 0.1", J2000 V = 23.75 +/- 0.2 DEC=-43D53'7.79" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the NED database. ------------------------------------------------------------------------------------------------------------------------------------ 19 NGC-3256E GALAXY, INTERACTING RA=10H28M5.6000S, J2000 V = 24.04 +/- 0.2 GALAXY, TIDAL TAIL DEC=-43D54'22.00" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 13 NGC-6872E GALAXY, TIDAL TAIL RA=20H17M21.9864S +/- 0.1", J2000 V = 24.06 +/- 0.2 DEC=-70D45'3.34" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the NED database. ------------------------------------------------------------------------------------------------------------------------------------ 15083( 5) - 13-Dec-2018 15:41:59 - [ 4] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 2 Primary_Pattern Secondary_Pattern Pattern_Type WFC3-UVIS-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.173 Line_Spacing 0.112 Coordinate_Frame POS-TARG Pattern_Orient 23.884 Angle_Between_Sides 81.785 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 15083( 5) - 13-Dec-2018 15:41:59 - [ 5] Visit: 01 Visit Requirements: ORIENT 349D TO 358 D; ORIENT 258D TO 268 D; ORIENT 78D TO 86 D On Hold Comments: Additional Comments: E tidal tail of NGC 1487.
