email fraud -- OT

I just received one of these fraudulent emails; fortunately, I didn't open the attachment. Thanks, Joe BEWARE OF SPAM! BOGUS DELIVERY MESSAGES E-MAILED TO POSTAL CUSTOMERS Some postal customers are receiving bogus e-mails about a package delivery. The e-mails contain a link that, when opened, installs a malicious virus that can steal personal information from your PC. The e-mails claim to be from the U.S. Postal Service and contain fraudulent information about an attempted or intercepted package delivery. You are instructed to click on a link to find out when you can expect your delivery. But Postal Inspectors warn: Do not click on the link! Like most viruses sent by e-mail, clicking on the link will activate a virus that can steal information—such as your user name, password, and financial account information. What to do? Simply delete the message without taking any further action. The Postal Inspection Service is working hard to resolve the issue and shut down the malicious program. If you have questions about a delivery or wish to report spam, please call 1-800-ASK-USPS.

Assuming two columns, Col. 1 is Col. A and Col. 2 is Col. B. This assumes that Columns A and B contain number formatted data and not text formatted data. Columns C and D are computed. Fill down formula for column C for number formatted data: =IF(A1=B1,A1,"Null") Fill down formula for column D for number formatted data: =IF(A1=B1,"Null",B1) Use find and replace to replace test string ``Null'' with a blank. If Columns A and B contain text formatted data, use the following fill-down formula variants: =IF(VALUE(A1)=VALUE(B1),VALUE(A1),"Null") =IF(VALUE(A1)=VALUE(B1),"Null",VALUE(B1)) - Clear Skies - Kurt

You can take my place on the list. Thanks.

magnitude and luminosity
by Gigi Giles 18 Nov '11

18 Nov '11

Hi Everyone, I'm puzzling over a little mathematical problem so I finally decided to ask for help! I am trying to calculate the individual masses of a binary system. I know the apparent magnitudes of the stars (4.03 and 6.00). I know the distance (5.128 pc). I know that luminosity is directly related to Mass^3.5. What I can't seem to do is calculate the luminosity of the components, given the apparent mag. I have determined that the absolute mags. are 5.48 and 7.45. I have even found a "luminosity calculator" on the web that gives me the figures (0.55 and 0.09 in solar units), but I really want to know the formula and to check if it is right. Any help please! thanks, Gigi
