... Time delay determinations in astrophysics are used most often to find time delays between flux density variations in different spectral bands and/or lines in AGNs, and different images of gravitationally lensed QSOs. ... OB used an idea to take into account the known gravitational lensing time delay to get combined radio and optical light curves and then to use them for determination of the possible radio-from-optical time delay. ... Correction for change of time delay and radio flux. ...

A time series analysis is applied to the photometric data obtained by the HST Fine Guidance Sensors (FGS), in order to discover new variable stars and to derive information about microvariability of a large sample of objects. ... Our project is based on a time series analysis of all data sets recorded by the FGSs in order to detect variability among the used Guide Stars. ... Based on ESO 1.5m Danish DFOSC photometry, we have verified variability for three Guide Stars. ...

... Tools . ... Instead, indentation with whitespace characters is used by the interpreter to identify which block a particular line of code belongs to. ... Lastly, the characters used to mark blocks (spaces and tabulators) are invisible (that s why they are usually only used for indentation and as separators), making it particularly hard to identify critical indentation errors and determine the indentation level of a particular line of code (e.g. the first line on a new page of printed Python code). ...
