These parameters would only be accessible through the sqlite version 2 database and not the version 1 psrcat. Added asymmetric uncertainties to database by using the tagToParameter table. tagString = 'asymmetricUncertainty'. For rvwc23, not added J1147+0829 since the position is given in galactic coordinates. For whx+23, pulsars J0625+17, J1826-00, J1827+00, J1854-01, J1858-02, J1907+0555, J1917+24, J1921+1540, J1929+1905, J1934+09, J1938+14A, J1943+28, J1958+2213, J2005+38, J2021+24, J2025+2133, J2041+46, J2108+41 do not exist in the database and coordinates given in galactic and thus not adding these pulsars and their data. For whx+23, J1836+09 is in psrcat with name J1836+0915, J1849+0340g is in psrcat with name J1849+0339g, J1852-0054g is in psrcat with name J1852-0055g, J1854-00 is in psrcat with name J1854-0036. Fixed error in sourceType and binaryType table where the citation_id and confidence were swapped. Added sourceType RADIO for J1312+1810E,J2208+4610,J1720-0533,J1953+1844. Added sourceType HE for PSR J1953+1844. |
| 2.2.0 | 2024/05/31 | 3630 | Added 96 new pulsars from flm+23, pbs+23, plj+23 and www+21. Move distance parameters from the 'distance' table to the 'parameter' table and removed the distance table. Fix spelling mistake in BSURF description in the 'parameterType' table. Set units to NULL for DTHETA. Previously was (-6). Changed P2 to F2 for J0045-7319 since psrcat2 supports the F2 parameter to match the publication. Update ULT description in the 'binaryTypeOptions' table. Delete HESS from 'associationType'. Add GL,GB,DIST,DIST1,R_LUM,EDOT,EDOTD2,B_LC,VTRANS,P1_I,AGE_I,BUSRF_I,EDOT_I,PMTOT,PMGL,PMGB to 'parameterType' table. J0205+6448 add citation bie06 to association SNR,PWN:3C58. J0540-6919 add citation aab+15 to association SNR:0540-693 and add PWN:0540-693. J1811-1925 add citation gs20 association SNR:G11.2-0.3. J1210-5226 add citation aaa+16a to association SNR:G296.5+10.0 and hg15 to association XRS:1E_1207.4-5209. J1952+3252 add citation ah21 to association SNR:CTB80. J2229+6114 add citation aaa+20a to SNR:G106.6+2.9 and add PWN:G106.6+2.9. Add survey Shallow L-band MPIfR MeerKAT Galactic Plane survey: mmgps-l. Updated declinations with 00:... to be +00:.... For mmb+23, the publication references PSR J1012+5703. By inspection we found this was J1012+5307 and tagged this occurence in the database. For pbs+23, PSR J1806-2125 is the name of an already discovered different pulsar. We have added an extra dec digit to name this pulsar J1806-21250 and tagged it in the database accordingly. Pulsar J1720-0533 already exists from www+21. The name is not being changed when inputting into the catalogue from mbz+23. 3 pulsars in dcm+23, which were input from the Arxiv paper have been renamed since we are now using the peer-reviewed publication for these discoveries. J0653+06 changed to J0653-06, J1130+09 to J1130+0921 and J1541+47 to J1541+4703. Updated 3 names for dcm+23 that were entered from the Arxiv publication. J0653+06, J1130+09 and J1541+47 are now J0653-06, J1130+0921 and J1541+4703. |
| 2.1.1 | 2024/04/03 | 3534 | Tagged pulsar J1357-2350 as having its name changed from J1358-2533 after it was redetected at a different position from the MWA SMART pulsar survey. Changed period of sbb+23 pulsars from miliseconds to seconds. |
| 2.1.0 | 2024/03/28 | 3534 | This is our first PSRCAT v2 data release in which we have added new parameters and pulsars. Previously new parameters would overwrite the older parameters, but now we can store multiple parameters per pulsar. In the v2 to v1 conversion (for the webpage, previous scripts etc.) we have chosen the most recently added parameter and the v1-format catalogue file contains comment lines describing where there was a choice. The updates made for this data release include: We have input new parameters and pulsars from bgf+23, ccp+23, crafts23, djk+23, gvf+23, lpz+23, sbb+23 and wyw+23. We have removed duplicated PMRA and PMDEC parameters for PSR J2047+1053 that were incorrectly entered into v1. We have updated the database schema to include a database version number for citations. We have improved storing information on database versions inside the schema. Flux and width parameters now have 'time derivative = 0' set. We have used database 'tags' to indicate papers that include incorrect parameters that have been fixed (for instance, a paper reported flux densities in mJy, but it should have been uJy) and pulsar names (a paper reported two new pulsars, but both with the same Jname and a paper also used an existing jname for a new pulsar). |
| 2.0.1 | 2024/02/27 | 3473 | Add missing DIST_A citation for J0834+2200 (Crab) and J1856+0113. Flux density from rfg+22 was in mJy, but should have been in uJy - divided by 1000 for J0514-4002A, J0514-4002B, J0514-4002C, J0515-4002D, J0514-4002E, J0515-4002F, J0514-4002G, J0514-4002H, J0514-4002I, J0514-4002J, J0514-4002K, J0514-4002L, J0514-4002M, J0514-4002N |
