This catalogue was founded near September,2003. Our aim was to collect full data on all known pulsars. Thus catalogue includes parameters bound up with radiation in different spectral ranges: radio, optical, extreme ultraviolet, X-ray and gamma. But parameters in radio range and parameters concerned with it were presented in ATNF pulsar catalogue during the begining of this database creating. For this reason we decided that main task of our catalogue would be reflection of complete information on pulsars properties in high energy band. Nevertheless catalogue includes data reflected in ATNF catalogue. We recognize that this information belong to ATNF and refer to it.

The instrument for work with catalog is query form on www.ioffe.ru/astro1/psr-catalog/Catalog.php. It is consists of two parts. The first in the top of the page is a list of the accessible pulsar parameters. Four general parameters are available at once. Other subdivides into several issues:"General and radio parameters of pulsars","Parameters of binary pulsars", "Parameters of optical pulsars","Parameters of euv pulsars"(euv means "extreme ultra violet"), "Parameters of X-ray pulsars" and "Parameters of gamma pulsars". Each of these issues is available after click on corresponding button. In this case you can see the roll of issue parameters. In the roll click on checkbox selects coincident parameter for output. Click on radio box assigns sorting parameter. Also there are two bottons allowing to check or to clear all output parameters from present issue. Again you can deselect all output and sorting parameters of issue by closing it. All accessible pulsar parameters described in the end of this file.

Beneath there is button "VIEW TABLE" for submit your query. After click on this button you get table with results. Action of other nearby buttons the following: "check all parameters" - opens all issues and checks all parameters for output
"clear all parameters" - clears all checkboxes, but not closes issues
"open all parameters" - opens all issues
"close all parameters" - closes all issues

The second part of form allows to set query conditions.
Firstly, it is possible to output not only the value of parameter, but also it's uncertainty in different forms and refer to the source of data. The following forms of uncertainty output are possible:"absolute uncertainty as integer" - an integer number representing uncertainty in last meaning figures of a value. (For example if value is:14.127 then uncertainty equal to 27 means 14.127 ± 0.027 ), "absolute uncertainty in usual look" - in the aforecited example it returns 0.027 and "relative uncertainty".

"Sort by" pull down list allows to set a way of sorting.

In the "User defined variables" division you can set up to four own variables. For this purpose it is necessary to assign variable C1,C2,C3 or C4 by inserting wishful expression in corresponding blank bar. After that it manages as common variable. Expression can contain other variables, following operators: +,-,*,/,% and following functions:
abs(x), acos(x), asin(x), atan(x), ceiling(x)(round fractions up),cos(x),cot(x), exp(x),floor(x)(round fractions down),log(x), log10(x), mod(n,m)(returns the remainder of n divided by m), pi(), pow(x,y), round(x,d), sign(x), sin(x), sqrt(x), tan(x), truncate(x,d)(returns the number x, truncated to d decimals)

The "Condition for values" bar is intended for input of conditions on pulsar parameters. In condition expression you can use: all variables; operators and functions determined in previous indent;comparison operators: =, !=, <=, <, >=, >;logical operators: !, &&, ||. Also available such additional functions:

exist(parameter)	returns only records where this parameter exists. Example: exist(p0)
error(parameter)	returns only records where absolute uncertainty as integer of this parameter exists. Due to this function you can impose condition on value of parameter absolute uncertainty as integer.Example: error(p0)<10
error	Due to this function you can impose condition on absolute uncertainty as integer value of all selected for output parameters.Example: error>10; if p0,p1,DM selected for output, it returns records where error(p0)>10 or error(p1)>10 or error(DM)>10.
abserr(parameter)	returns only records where absolute uncertainty of this parameter exists. Due to this function you can impose condition on value of parameter absolute uncertainty.Example: abserr(p0)>0.00001
abserr	Due to this function you can impose condition on absolute uncertainty value of all selected for output parameters.Example: abserr>0.00001; if p0,p1,DM selected for output, it returns records where abserr(p0)>0.00001 or abserr(p1)>0.00001 or abserr(DM)>0.00001.
relerr(parameter)	returns only records where relative uncertainty of this parameter exists. Due to this function you can impose condition on value of parameter relative uncertainty.Example: relerr(DM)<0.001
relerr	Due to this function you can impose condition on relative uncertainty value of all selected for output parameters.Example: relerr<0.001; if p0,p1,DM selected for output, it returns records where relerr(p0)<0.001 or relerr(p1)<0.001 or relerr(DM)<0.001.
refer(parameter)	returns only records where reference of this parameter exists. Due to this function you can impose condition on value of parameter reference. Example: refer(DM)=hlk+03 (Caution: don't put quotes around of the reference name)
type(parameter)	Returns only records in which Type field string contains parameter. Example: type(X) returns records with type 'XR' or 'AXP'.
assoc(parameter)	Returns only records in which Assoc field string contains parameter. Example: assoc(SNR) returns records describing SNR's.
rtelescope(parameter)	Returns only records in which RTelescope field string contains parameter. Example: rtelescope(Are) returns records with radio telescope 'Arecibo'.
xtelescope(parameter)	Returns only records in which XTelescope field string contains parameter. Example: rtelescope(Bep) returns records with x-ray telescope 'Beppo-SAX'.

"Pulsars names" textarea enables to select pulsars with wishful names. It is possible to enter several names divided by comma,semicolon,space or enter. Also it is possible to use symbols '?' that matches any character one times and '*' that matches any character zero or more times. Example: b0833-4?,*17. Pull down list in the right of textarea allows to select kind of names .

Last division allows to select pulsars from circular area. For this purpose it is necessary to set centre coordinates and radius. If radius didn't set then by default it is considered equal 180 degrees. The acceptable kind of centre coordinates depends on value of pull down list taking in the top of division. In the case of 'J2000 coordinates' it is HH:MM:SS.sss in range from 00:00:00.00 to 23:59:59.9(9) for right ascension and sDD:MM:SS.sss in range from -90:00:00 to +90:00:00 for declination.In the case of 'J2000 coordinates in degrees' it is DD.ddd in range from 00.00 to 359.9(9) for right ascension and sDD.ddd in range from -90.00 to +90.00 for declination. In the case of 'Galactic coordinates' it is DD.ddd in range from 00.00 to 359.9(9) for longitude l and sDD.ddd in range from -90.00 to +90.00 for latitude b. Also here you can include to output parameters pulsar distance from centre of the circle.

In the bottom of the query form there is "VIEW TABLE" button. It's action completely coincides with action of the same button on the top of the form. "clear all conditions" button clears all conditions from the second part of the query form.
