Please, substitute this paragraph :

In 1968 (10 November), Lovelace and his collaborators discovered period \(P\approx 33\) ms of the Crab Pulsar.[1] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [2] which was adapted to run on the Arecibo Observatory's CDC 3200 computer. [3] This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar.[4] A few weeks earlier, observers from the National Radio Astronomy Observatory reported about two pulsating sources near the Crab Nebula, with no evident periodicities.[5][6] Lovelace and collaborators found that one of pulsars (the NP 0532) is located in the center of the Crab Nebula and found it's period with a high precision: 33.09 ms.[4]

With the new one (below). In the new version, I added a reference after the 1st phrase (because Lovell (1973) book described only a part of the 1st phrase). Now, both references cover the content of the 1st phrase.

Older modifications

In 1968 (10 November), Lovelace and his collaborators discovered period \(P\approx 33\) ms of the Crab Pulsar.[9][1] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [2] which was adapted to run on the Arecibo Observatory's CDC 3200 computer. [3] This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar.[4] A few weeks earlier, observers from the National Radio Astronomy Observatory reported about two pulsating sources near the Crab Nebula, with no evident periodicities.[5][6] Lovelace and collaborators found that one of pulsars (the NP 0532) is located in the center of the Crab Nebula and found it's period with a high precision: 33.09 ms.[4]

This was the fastest pulsar found at that time.[1][10] This discovery helped to proof the idea that pulsars were rotating neutron stars.[11][12] Before that, many scientists believed that pulsars were pulsating white dwarfs or neutron stars.[12][13]

Please, add reference at the end of this phrase:

Dear Editor,

Please, substitute this paragraph:

In 1968 (10 November), Lovelace discovered period \(P\approx 33\) ms of the Crab Pulsar.[14]Template:Better source needed As a graduate student working at Arecibo Observatory, Lovelace developed a Fast Fourier transform program.[15]Template:Better source needed The special code named Gallop in Fortran was adapted to run on the Arecibo Observatory's CDC 3200 computer, which had a memory of 32,000 words of 24 bit length.Template:Citation needed The code was integer-based, using half-words of 12 bits, and was able to do the fast Fourier transform of N=16,384 signal samples.Template:Citation needed The 8192 signal power values were printed out on a folded raster scan.Template:Citation needed The signal to noise ratio increases as N increases.Template:Citation needed This was the largest value of N that could be handled by the Arecibo computer.Template:Citation needed This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar, which is approximately 33 ms (33.09 ms).[14]Template:Better source needed

With a new one, where I found better sources and removed numbers associated with the numerical code and computer (there are no references to these numbers, and overall - it is better without them). Instead, I added a bit of history associated with work of other people.

Please, substitute this paragraph:

This was the fastest pulsar found at that time.[1][16] This discovery helped to cement the idea that pulsars were rotating neutron stars.[11][12] Before that, many scientists believed that pulsars were pulsating white dwarfs or neutron stars.[13][17]

With the new one below. In the old text, I do not like the phrase: "helped to cement the idea". I substituted with the phrase: "helped to proof the idea".

This was the fastest pulsar found at that time.[1][18] This discovery helped to proof the idea that pulsars were rotating neutron stars.[11][12] Before that, many scientists believed that pulsars were pulsating white dwarfs or neutron stars.[12][13]

In addition, please substitute this phrase:

with a new one, where I added requested reference:

and in 2010 became an editorial board member of "Journal of Computational Astrophysics and Cosmology".[8]
