Re: collected information on Mark IV data analysis

Hello Michael R.

GSC 0763 0058 in long suspect list:-

Thanks to Patrick Wils' copy of Taichi Kato's newvar.cat being a couple
of months more recent than mine I now know that in the list of 25
suspected objects, GSC 0763 0058 at 07 18 18.0 +08 57 29 was previously
suspected of variability by Bernhard in March 2002, being BrhV109 in his
list, based on around half a dozen datapoints.
(It could either be deleted from the list or simply have = BrhV109 added
in the notes column).

GSC 00763-0058 in individual list:-

Similarly, in the group of individual stars of interest, GSC 00763-00572
was reported as being of suspect variability by Bernhard in February
2002, being BhrV103 in his list.  For this one he has one long run
covering around half of one cycle just a couple of nights before Tom's
_last_ night of measures for it.


GSC 00175-02509 in individual list:-

I asked Chris Lloyd to independently check the data for this one and he
came up with a couple of slightly shorter possible periods, as well as
noting that an EW solution of roughly twice the period was also
possible.


Additional :

Carbon star GSC 00144-01654 = CGCS 1214 at RA 094.0274 DEC +06.7774 is
probably a long period variable

Carbon star GSC 00190-00120 = CGCS 1749 at RA 113.0417 DEC +05.8321 is
probably a long period variable, almost constant in the far red, varying
more the bluer the passband (related to RCB???)

(http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-newvar/msg01458.html)


[These latter two were also posted to TASS list, but it's easier for me
to find the above urls]



OTHER:

GSC 00684-01316 is probably NSV 16176


Cheers
