Request for Information on how to make a FITS Image
I know that at the end of the Receivers in Radio Telescopes, after the final Amplifier the analog signal will be given to the ADC. Now this ADC converts the analog signal into a stream of binary bits. ...

Why Nyquist Sampling Rate depends on Bandwidth and not max frequency?
Is the Nyquist sampling rate same for different bands if those bands have same bandwith? E.g. Would the Nyquist Sampling rate be same for 1000-1400 MHz band as for 100-500 MHz band because both the ...

Do ASKAP and ALMA have "fast dump" interferometric modes? Can they see and perhaps report Fast Radio Bursts in real time?
Chatterjee et al 2017 The direct localization of a fast radio burst and its host nicely shows a VLA detection of a repeating FRB in 5 millisecond steps nicely demonstrating the dispersion slope ...

How to find period of a pulsar from a given time sampled voltage data?
I've a data file with 2 columns, each containing time sampled voltage output (a sequence of real numbers) from a radio telescope, so there is a pair of telescope which are measuring the signal here. ...
