# My new wlq sources from plotkin 2010 and mb14 

1) First we have taken 86 RQ-WLQ from sources from table 6 from plotkin et.al 2010  and 46 rqwlq sources from MB14 2014. Which leads to total number of 132 wlq sources.
2) Afer that we have checked how many sources are common in between plotkin and MB14, and we found that there are 9 sources which we found common between plotkin and MB14, which leads to total number of sources upto 123 wlq .
3) After that we have applied the radio flag i.e we have neglected those sources whose R parameter value <10 or not detected in FIRST. Since we have checked this condition in MB14 sources only here we found 15 sources with r>10 as we have no information regarding the radio loud parameter values in plotkin sources but as he published in his paper the genuine 86 RQWLQ sources so we have considered all of his sources as radio quiet. Which leads to total number of WLQ sample sources upto 108.
4) Then we have checked for the availability of  WISE data among these 108 sources. and we have found that there are almost 98 sources for which we have found the wise data.
5) In these 98 wlq source we have found five galaxies as identified from there spectrum:The list is as follow
**101754.91+431201.1**
**114038.91+100535.3** 
**140916.33-000011.2**
**141200.04+634414.9**
**163322.48+422738.8**
6) So we have left with 93 rqwlq sources.

7) In order to remove the galactic sources we have checked for the proper motion of the sources within 2.5$\sigma$, and we have found that following sources are found to have pm > 2.5 $\sigma$. 
**025743.72+011144.5    10.00 ± 3.606
085626.63+494852.2      10.20 ± 3.606
100902.83+621354.8      10.00 ± 2.236
103105.72+173524.6      8.00 ± 2.828
111401.30+222211.4      10.20 ± 2.000
121929.45+471522.8      112.07 ± 3.606
124745.39+325147.0      15.62 ± 5.000
134052.43+074008.1      05.66 ± 2.236
144803.36+240704.2      12.81 ± 5.000
164903.28+304936.5      10.00 ± 3.606
165806.76+611858.9      272.62 ± 16.553
224749.57+134248.1**    **14.14 ± 3.606**
9) 12 out of them have proper motion above the condition and are detected as galactic objects.
10) Sources that are found in the optically crowded region are as follow:
**090843.25+285229.8,100517.54+331202.8,145604.18+544253.1,151554.81+251334.0**
12) So finally we have got our sample of 77 RQWLQ with proper motion <2.5$\sigma$. 
13) Out of 77 rqwlq we have found that 8 of the wlq are not matching our control sample because of their high redshift or very smalll redshift, the list is follow:
**For high redshift:**
**083413.90+511214.6------- 6.26
093544.16+124031.6 -------- 6.5
114153.33+021924.3  ------- 3.48
142601.30+243245.7 -------- 4.65
145514.09+235337.6 -------- 6.38**
 **For low redsfift:**
 **141730.92+073320.7 ----- 0.056
 161245.67+511816.9  ------ 0.08
 172858.16+603512.7 ------- 0.063**
 
## Final Sample
We have the final list of 69 RQWLQ.
We have also make the control sample of the weak line quasar in which for each wlq we have 55 qsos matching in the optical spectra with the tolrance of 0.01 in redshift and 0.6 in r_mag.
