[[PageOutline]] = Heather's PS1 Seminar = Introduction to PanSTARRS Data products ---- == Outline == The talk is on the wiki, please click on interesting links, please play with your computers (as long as it involves ps1), please ask questions! I will cover: * Computer Resources * Help! * How to get to the Pixels * How to get to the Catalogs ---- == Computer Resources == Advertisement: we have a machine, called 'ifaps1' which is mostly unused. It has access to various ps1 machines, it has access to various ipp tools. * Who can access it: anyone with a galileo account * How to set it up: Follow instructions here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/IPP_on_ifaps1 * we also have an idl license for it * useful to use our tools (and cfitsio) - useful for running psphot, or for funpack (to unzip the compressed files) * warning: you have to access it from within the ifa network (ie, not from home) ---- == Where to get help == First step look at the wikis, if need more information ask people === Wikis === * ps1sc wiki http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/Main_Page * ipp wiki main page (and this page): http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/ , specifically the part for 'IPP users' * psps wiki http://web01.psps.ifa.hawaii.edu/psps-trac/wiki/PSPSNews === People === These are the people in ipp/psps, (heather) has labeled them: * ken - psvo * gene - dvo / 3pi * mark - md * bill - postmaster (postage stamp server) * chris - grand reprocessing * heather - psps / skyprobe * conrad - psps * thomas - psps Ask any of us questions. If we don't know we probably know who to ask :) ---- == Surveys == Most in this room will likely use one of 2 surveys: === 3pi survey === Three Pi has covered everything north of dec = -30 in grizy === Medium Deep (MD) survey === Medium Deep survey is ~ 12 spots in the sky with a lot of coverage in time: ||Field #||Name||Alt Name||RA (J2000)||RA (deg)||Dec (J2000)||Dec (deg)||Comment|| ||00||PS1MD00||M31||00 42 42||010.6750||+41 16 00||+41.2667||M31.

This is just a generic guess, other stages may suit your needs better. === Different ways to get pixels === * Postage Stamp Server * good to grab your specific patch of sky * access here: http://pstamp.ipp.ifa.hawaii.edu/request.php * wiki here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/PostageStampServer * warning - might not work from home (might need to be from within ifa network) * Datastore * good to grab stuff automatically (we put data on there as we process it) * Ask * good for skyprobe (eventually skyprobe will be accessed similarly to gpc1) * good if you need data that the postage stamp server doesn't have (ie, detrends? other stuff?) ---- == How to access the catalogs == Different ways, depends on your needs: * PSPS * access through http://web01.psps.ifa.hawaii.edu/PSI/login.php * preferred way because it's easy * can use PSVO * information on the flags: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/PSPSFlags_SAS10 * general psps information: http://web01.psps.ifa.hawaii.edu/psps-trac/wiki/PSPSNews * con: limited data in it now (will have more soon) * Postage stamp Server * grab catalogs or images of individual exposures * easy to use * not good for searches over the whole sky, best when you know what patch of sky to look in * easy access here: http://web01.psps.ifa.hawaii.edu/PSI/login.php (look for postage stamp) * other access here: http://pstamp.ipp.ifa.hawaii.edu/request.php (from within ifa network) * wiki here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/PostageStampServer * dvo (see Gene) * covers the whole sky * hard to use * see wiki : http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/DVO_TopLevel ---- == Other PS1 stuff == * skyprobe - sees everything that ps1 sees, but with a smaller less sensitive camera (this is good for bright stars) - filters grizy * see skyprobe pages : http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ISP * UIP - sees everything that ps1 sees, but in u band (Not yet) * see UIP pages: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/UIP * spectroscopic sky probe (ask John Tonry) * see SSP pages: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/SSP
