Allen, Jan 30, 2003 These directories contain supporting files for the AVO 1st year prototype demonstration release to the Science Working Group. These files are not required to run the demo software. Included here is a small set of tables, scripts and filters which can be loaded into the prototype. The click-by-click description of the demo, and also the tutorial notes make references to these files. They represent examples which can be used as templates or starting points, to help users construct their own. The demo_extras files are split into two tar files. demo_extras.tar.gz contains the tables and scripts, and demo_extras__data.tar.gz contains a small set of data. The intended directory structure is /Aladin /demo_extras /data /scripts /tables It is recommended to unpack demo_extras.tar.gz which will make the ./demo_extras directory (including scripts and tables), and then unpack demo_extras_data.tar.gz which will add subdirectory ./demo_extras/data. 1. TABLES --------- /demo_extras/tables/ hiz.tsv : A tab-separated value table containing the positions of candidate high redshift objects in the CDF-S. Object 3 in this table is the "red object" shown in the Jodrell Bank demo presentation. transients.tsv : A tab separated value table containing the positions and other information about the transient objects (Supernovae candidates) identified in the ACS images of the CDF-S. This file was generated from the information on the GOODS-ACS web page: http://www.stsci.edu/ftp/science/goods/transients.html These files can be loaded either by typing e.g. load ../demo_extras/tables/hiz.tsv in the Aladin window, or by using the "LOCAL" load function in the the server selector window. 2. SCRIPTS and FILTERS ---------------------- /demo_extras/scripts The three main files in this directory are: dropouts.ajs, up_limits.ajs, and hdfn1.ajs. dropouts.ajs - a script which loads the filters u_drop.ajs b_drop.ajs v_drop.ajs r_drop.ajs i_drop.ajs k_drop.ajs - these filters provide logical expressions for defining e.g. U-band dropouts using catalog magnitude values, here designed for the EIS draft colour catalogs. - each of the individual filters may be loaded separately. dropouts.ajs calls loads all the filters simultaneously. - to apply these filters one must of course have loaded a suitable catalog to apply the filter to. To apply to another catalog one can simply change UCD or column name references as described in the filters manual. - load this script by typing load ../demo_extras/scripts/dropouts.ajs up_limits.ajs - a script which loads filters u_lim.ajs b_lim.ajs v_lim.ajs r_lim.ajs i_lim.ajs k_lim.ajs - these filters are similar to the dropout filters, but this case they identify objects in the EIS catalog whose values are upper limits. - load this script by typing load ../demo_extras/scripts/up_limits.ajs transients1.ajs, transients2.ajs - two filters which make use of the tables/transients.tsv file. - these filters simply show the transients' names as listed in the transients.tsv file. - transients.tsv must be loaded for these filters to apply to. - load these filters by typing, e.g. load ../demo_extras/scripts/transients1.ajs hdfn1.ajs - a script which loads data, catalogs and filters in the region of sky centered on the Hubble Deep Field North. This is designed to show examples of: i) loading local files from a script ii) loading DSS images from the aladin image server from a script iii) generating an RGB image from a script iv) loading VizieR catalogs from a script v) loading a set of filters from a script This script relies on the local data, also provided with these supporting files in the demo_extras/data directory. This script loads a total of about 70MB of data, so is relatively memory intensive and may fail on machines with less than this amount of memory. The script takes approximately 3 minutes to fully load (on a 1.8Ghz Linux machine with 1GB of memory) The filters loaded in this script, are designed to be applied to a catalog with redshift measurements. The filters "filter" the catalog values into redshift bins (z0.ajs, z1.ajs, z2.ajs, z3.ajs, z4.ajs, z6.ajs) and also draw circles around the objects with radii proportional to the redshift value (z_circle.ajs) - load this script by typing load ../demo_extras/scripts/hdfn1.ajs General notes on filters and scripts ------------------------------------ Filters and scripts must be given .ajs filename extensions as is described in the Aladin manual. Scripts may only be loaded using the main Aladin text window, attempting to load via the LOCAL button may crash the prototype. Filters can of course be defined using the "filters" button in the visualization window, which brings up the filters interface. One has the possibility of using the predefined filters as a starting point. Also once a script filter is loaded, it may also be edited in the interface. @ 1.2 log @Instructions for using the supporting files @ text @d3 3 a5 3 demo_extras/tables - contained in demo_extras.tar demo_extras/scripts - contained in demo_extras.tar demo_extras/data - contained in demo_extras_data.tar d24 2 a25 2 demo_extras.tar contains the tables and scripts, and demo_extras__data.tar contains a small set of data. d35 3 a37 3 It is recommended to unpack demo_extras.tar which will make the /demo_extras directory (including scripts and tables), and then unpack demo_extras_data.tar inside /demo_extras. @ 1.1 log @Instructions for using the supporting files @ text @d20 1 a20 1 which can be used as templates or examples, to help users d35 3 @
