                                     In circular patches

The 2MASS stars are sorted by V(J,K) (from bright to faint), where
V(J,K)=K+2.0*((J-K)+0.14)+0.382*exp((J-K-0.2)*2).

Stars were proposed in 11 degree radius within (ra,dec)=(101.7482,21.37975).
This is because the boresight coordinates were not fixed during 
the preparation of the proposal.

The 2MASS stars were selected with following 
criteria on their quality of photometry.
(qflg=='AAA')&(bflg=='111')&(cflg=='000')&(xflg==0)&(aflg==0)

File description
---------------------------------------------------------------------
columns: [epic, id, ra, dec, jmag, hmag, kmag, vmag_jk, tflag, pflag]
epic  -  is -1 for stars not selected by K2
id    -  2MASS id of stars 
ra    -  2MASS RA 
dec   -  2MASS DEC
jmag  -  J  mag from 2MASS
hmag  -  H  mag from 2MASS
kmag  -  Ks mag from 2MASS
vmag_jk- V(J,K) from 2MASS J and Ks
pflag -  priority flag, related to type of source for the star
tflag -  is a 32 bit integer used to store flags that identify 
         the different type of targets. Bitmasking is used as follows. 
         APOGEE  ((tflag&(2**0))   !=0)  
         RAVE    ((tflag&(2**1))   !=0)  
         GAIAESO ((tflag&(2**2))   !=0)
         MISC    ((tflag&(2**3))   !=0)
	 UNUSED  .......4 to 9........   
         2MASS   ((tflag&(2**10))  !=0) main proposed targets 
---------------------------------------------------------------------
Epic catalog was not available during the preparation of the proposal.
The proposed stars were cross matched later on with stars selected 
by K2. So, stars not selected by K2 have epicid=-1.
