A confirmation of this important result urgently needs excluding possible source confusion which could in principle account for the unusual broadband spectrum. We propose joint Chandra/ACIS-I (10ksec) and HST-WFC3UVIS (2000s) observations in order to validate this multiwavelength association, which is not trivial in this crowded field close to the Galactic plane. Deep imaging in the optical and X-rays is crucial for understanding the physical nature of this exceptional object and can only be addressed by these instruments requiring high angular resolution and low background. ------------------------------------------------------------------------------------ Observations Description ------------------------ 1 orbit of HST/WFC3/UVIS imaging of target ------------------------------------------------------------------------------------ 13946( 2) - 30-Oct-2014 15:31:08 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 PMNJ1603-490 GALAXY, ELLIPTICAL, RA=16H03M50.6900S, J2000 Z = 0.18 V = 25 +/- 1 4 JET, QUASAR, RADIO DEC=-49D04'5.49" GALAXY Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 13946( 2) - 30-Oct-2014 15:31:08 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 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 ------------------------------------------------------------------------------------------------------------------------------------ 13946( 2) - 30-Oct-2014 15:31:08 - [ 4] Visit: 01 Visit Requirements: On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 PMNJ1603-49 WFC3/UVI ACCUM UVIS1-FIX F625W 1 650 S PATTERN 1 1 04 S (2600 S) ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ PMNJ1603-4904 1 WFC3/UVI ACCUM UVIS1-FI F625W 1 none none none 1 N/A S X PMNJ1603-4904 1 WFC3/UVI ACCUM UVIS1-FI F625W 2 none none none 1 N/A S X PMNJ1603-4904 1 WFC3/UVI ACCUM UVIS1-FI F625W 3 none none none 1 N/A S X PMNJ1603-4904 1 WFC3/UVI ACCUM UVIS1-FI F625W 4 none none none 1 N/A S X 13946( 2) - 30-Oct-2014 15:31:08 - [ 5] Summary Form for Proposal 13946 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Apertures UVIS1-FIX ------------------------------------------------------------------------------------------------------------------------------------ Configurations WFC3/UVIS ------------------------------------------------------------------------------------------------------------------------------------ Opmodes ACCUM ------------------------------------------------------------------------------------------------------------------------------------ Optional Parameters ------------------------------------------------------------------------------------------------------------------------------------ Special Requirements PATTERN 1 1 ------------------------------------------------------------------------------------------------------------------------------------ Spectral Elements F625W ------------------------------------------------------------------------------------------------------------------------------------ Target Names PMNJ1603-4904 ------------------------------------------------------------------------------------------------------------------------------------
