This example demonstrates an event that I've seen throughout December 2011 and January 2012 on PM1THV1T:

impska

# Collect 2 data sets that differ only by the end date
x1=fetch.Msid('pm1thv1t','2011:350:00:00:00.000','2011:353:00:00:00.000')
x2=fetch.Msid('pm1thv1t','2011:350:00:00:00.000','2011:356:00:00:00.000')

# Plot results
figure(1)
plot_cxctime(x1.times, x1.vals)
title('Dataset w/ End Date of 2011:253:00:00:00.000')
disp('x1 Last Entry: ' + Chandra.Time.DateTime(x1.times[-1]).date)

figure(2)
plot_cxctime(x2.times, x2.vals)
title('Dataset w/ End Date of 2011:256:00:00:00.000')
disp('x2 Last Entry: ' + Chandra.Time.DateTime(x2.times[-1]).date)

Query #1 produced no data for 2011:252. However, this data is available on Query #2.
