`survey` – Read a survey file into a survey object¶

class survey.Survey¶

Survey.__init__(surveyName)¶: Read in a (correctly formatted!) survey file

Survey.__str__()¶: Define how to perform print Survey

Survey.nchans()¶

Returns the number of channels, calculated as

$n_{\rm{chans}} = \frac{ {\rm{BW}}_{\rm{total}} }{ {\rm{BM}}_{\rm{chan}} }$

Survey.inRegion(pulsar)¶: Determines if Pulsar is inside survey region. Returns True or False accordingly

Survey.inPointing(pulsar)¶: Determines if Pulsar is inside one of the survey’s pointings. Returns the offset from beam centre to the pulsar.

Survey.SNRcalc(pulsar, pop)¶

Calculates the SNR of a Pulsar from Population pop in the survey. Returns -1 if pulse is smeared, and -2 if pulsar is outside survey region. SNR is calculated (with familiar terms) as

${\rm{SNR}} = \frac{S_{1400} G \sqrt{n_{\rm{pol}} BW \tau}}{\beta T_{\rm{tot}}} \sqrt{\frac{1-\delta}{\delta}} \eta$

where

$\eta = \exp(-2.7727 \times {\rm{offset}}^2 / {\rm{fwhm}}^2)$

class survey.Pointing¶

Pointing.__init__(coord1, coord2, coordtype)¶: Converts (coord1, coord2) into correctly formatted (l, b). Coordtype must be either eq or gal. If eq, the RA and Dec are converted internally
