Download Izmccd (~2.7 MB). Solution of problems at identification of star field. ... 2) Scale is not correct. ... In this case algorithm of identification will revise all values of scale from twice smaller up to twice greater. ... There should be more than value of the field "Number of stars in frame". ... The star field is considered identified if number of the identified stars more or equally to this value. It is necessary to set value from 4 up to value of field "Number of stars in frame". ...

Table 5.1: Special External Target Names . ... The Visit and Exposure Specifications are used to define the proposed exposures for all the Scientific Instruments. ... The rest of the exposure keywords are used to define parameters that usually change from one exposure to the next, such as filters, exposure times, and special scheduling requirements. ... An exposure consists of the events and data corresponding to a unique Exposure_Number within a given visit. ... Science exposure(s) . ...

... Please note the following problems and workarounds: . ... Arrow keys . Arrow keys are used in SAOtng to move the mouse or markers. ... Unfortunately, error messages are generated if both sets are defined in the SAOtng code but are not supported by X. To get around this problem, we have added the -kbprefix command switch (and the SAOTNG_KBPREFIX environment variable) to SAOtng. This switch allows you to specify which arrow keys you want to use (assuming your version of X supports both). ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

... If the star names used in data files are not exactly the same character strings as those used in star files, the reduction program will try to make cross-identifications. ... The program applies these rules in attempting to parse name strings containing multiple designations that are not separated by the `` = '' string (surrounded by blanks). ... This situation can be avoided by making sure that all star names are spelled consistently, and that names in star files agree with names in data files. ...
