----- Attempting Submission 4 (Wed Mar 31 23:57:40 GMT 2021) -----The most massive low density globular clusterWe propose to make a Chandra observation of a newly discovered high mass, low density globular cluster. This cluster has properties largely similar to that of Omega Centauri in terms of its stellar mass and its ratio of tidal to core radius, but its characteristic radii are a factor of about 3 larger than Omega Cen's. As a result, this is the first Milky Way cluster for which the stellar density is small enough that dynamical formation and destruction of close binaries will be unimportant, while having a large enough stellar mass that it can be expected to show some interacting binaries anyway. It will be the first object that can be used to characterize the baseline rate of production of these systems in a low metallicity, old stellar population.This proposal is to do a 2*2 mosaic with WFC3. Each observation will have 1000 seconds each in 300X and 606W, and 245 seconds in 814W. We note that in finalizing this proposal, we discovered a typo in the coordinates for the object of interest and have fixed that, which is the reason for the mismatch.n/aStellar Physics and Stellar Types6falsefalsefalsefalsefalsefalsefalseSUPPORTEDSTELLAR CLUSTERGLOBULAR CLUSTERYESThe apparent magnitude of 7 is integrated over a region somewhat larger than the mosaic we propose to observe.J2000J2000WFC3/UVISImagingNoNoF300XWFC3/UVISImagingNoNoF814WWFC3/UVISImagingNoNoF606WPOS-TARGDITHER0.135LINEfalsefalse346.84WFC3-UVIS-DITHER-LINE-3PT1falsePOS-TARGDITHER0.145LINEfalsefalse246.84WFC3-UVIS-DITHER-LINE2falseHst Same orient constraint links visits (05 06 07 08)The scheduling data was generated by CASM 28.2.CASM was run in Phase II mode.C:\Users\Tom\AppData\Local\Temp\OPVisit5635375283020059492.xmlThis is a modification of Visit 01 as an example of using a 3-point dither for the 300X exposures and a 2-point dither for the 606W exposures, in each case replacing the cosmic-ray-split pairs of exposures. The dithers generally give a better result because they can help get rid of bad pixels or columns, and 3-point dithers give better results than 2-point dithers (or CR-split pairs). The revised visit 05 has slightly greater total exposure time in 300x, a bit less in 606W, and the same in 814W. The minimum time is 353 s to fit parallel buffer dumps in during exposures; that's why we use that.
Note that if you prefer this example Visit 05 in place of Visit 01, you should replace Visit 01 with it, and then modify Visit 2, 3, and 4 accordingly. Be careful to retain the POSTARGs so that you get your 2x2 mozaic. You may need to cut and paste the X and Y POSTARGs from Visits 2, 3, and 4 that were defined by the mosaic template. You can verify the layout using Aladin's view.(Tic-Visit
