Usage of The TASS MarkIV Engineering Run DatabaseFor example, let's investigate a star at R.A. 18h57m29s.84, Decl. +20o05'27".3. The TASS MarkIV Engineering Run Database provides two ways of search methods. One is to search star list of the target field. Another one is to search all observations of the target star. Search Star ListOpen the following page. The TASS MarkIV Engineering Run Database (Star List) Then the page to input the parameters will be displayed. So input the required parameters.
Push the "Get Stars" button, and the star data will be displayed. Note that all star data within the search field are displayed, so find the correct data based on the R.A. and Decl., or the brightness. The V magnitude displayed here can be used as comparison stars for visual observations of comets, novae or variable stars. In the case of observation of comets, the ICQ code is "TA". However, select the data observed many times enough, based on the number of observations. If the standard deviation is large, the star can be variable and you should check the light curve. Search All ObservationsOpen the following page. The TASS MarkIV Engineering Run Database (Download Data) Then the page to input the parameters will be displayed. So input the required parameters.
Push the "Get Data" button, and the observation data will be displayed. Note that observations of all stars within the search field are displayed, so find the correct data based on the R.A. and Decl., or the brightness. The data is in TAB-separated text file. Save it into a text file by the browser and open it using Excel, then the light curve will be displayed. |
